  1. I had a few minutes last Wednesday after work, so I got the bumper pulled off to check out the damage. It really doesn't look bad. A little bit of bent metal that I think I can hammer back into shape, and some new rivnuts, then I should be good to go. The much thicker under tray is totally fine, it's just the vertical mounts that bent. It looks like a plastic clip or two got trashed, but NBD. I may be at home next weekend, so hopefully I can get everything put back together. That give me time to order some parts I need, like brake rotors and the brake pedal travel sensor (which I'm told may be the issue with my ABS).
  2. Wow, speaking of design flaws...
  3. I love this build. Totally noob aero question here. What does having the whole front grill smooth(ish) like that accomplish without some sort of splitter? I get with a splitter that high pressure zone will help push the splitter down, but I don't get what it's doing in this instance.
  4. Temp on the car were awesome, even in the heat. Coolant max was 205, Oil max was 222. I had some issues with understeer on Saturday. I tried higher and lower tire pressures with no noticeable difference. Then I did what I should have done sooner and asked someone who knows about car setup what to change. Adam at Doghouse had several suggestions. I softened up the front dampers a bit (single adjustable konis). Things seemed a little better, but not a ton. I rolled down to Doghouse again and Adam threw it on the lift to soften the front sway bar. This helped a bit more, but I still couldn't get the throttle rotation I wanted. I stiffened the rear dampers, and all of a sudden I had some throttle rotation back. I really had to work on some self control and finesse this weekend. Without a ton of HP, I can really just mash the throttle in a lot of instances. This weekend that would just cause the front to start pushing, particularly in places like wagon wheel and horse shoe. I had to hold my maintenance a bit longer and roll into the throttle, then things were better. A friend of mine came out Saturday to go for a ride. He made it through 8 laps before he thought he was going to get sick so I feel like I did my job on that one. Oil consumption seemed pretty standard. I probably added 2 quarts this weekend which is normal. Tires are pretty low, but I do have 5 days on them now. Their fast days are behind them, but I have the RS4s ready to go so I'll run these to the cords. I had some strong shuddering under hard braking which is a new development. I'll measure the rotors, but I'm pretty sure these are the ones I put on there when I got the car so I'd feel fine replacing them. The carbotech pads still have plenty of meat left. When I was pulling the car off the trailer Sunday evening, I didn't realize the front lip had caught so it nearly ripped the bumper off. The mount for the Motion Motorsports undertray got all bent up and ripped out one side. That put me in a super great mood. I can probably bend it all back and remount everything. I don't have a weekend at home for at least a few weeks, but I'll get around to it some day. The pictures are after I pulled on things a bit to stop it from rubbing on the tires so I could get it in the garage.
  5. Yeah, you're right. Nothing surprising there at all, I am not the first person to discover this behavior. @joesurf79, I saw you coming off track several time when I was sitting on the grid (sometimes with a grill full of grass). I wanted to come by and say hi but I think you were busy with instructor stuff.
  6. MSR-C 1.7 CCWDate: 7/13/2019Lap time: 1:24.83 (AIM)Car: 1995 BMW M3Vehicle weight with driver: ~2900 lbsWheel horsepower: ~250Tires: 245/40-17 RE-71REstimated ambient temperature: 90 degrees 1/100th faster than my best going the other direction on these same tires. Race studio says there's 2.5 seconds out there with my current splits, but I'm not going to find it on these tires. It feels like the grip really drops by lap 6-7. By lap 9 it's pretty greasy, especially in this heat. But it takes me time to get comfortable with everything again. The car wants the fast laps early, but I feel more in the groove later. With speed differences on warm up laps, records are going to be hard to set in HPDE.
  7. I did a small brake flush yesterday when I got home. I don't expect it will make a difference in the pad knock back issue I think I was getting, but it won't hurt. Didn't see any bubbles come out, so that was good. Checked and topped off the oil too. I need to order some new filters and I'll toss one in there soon. I chickened out on the RC1s after seeing people talk about them not handling high ambient temps very well (Texas summers, lol). I ordered some RS4s in 255/40-17 last Friday. They were at the door today. These will be the backups in case I cord the RE71s, which are being flipped on the wheels. Maybe I should add some more camber back to the front. I'll see how things go this weekend. I also found the risers for the rear spoiler, so obviously I added those back. It looks like they add a little bit more angle as well. I'm sure any added down force (lol) can't possibly be worth more than the drag this adds, but I like how it looks so whatever. When I get wheels and tires back on I'll get it washed, which it needs terribly. It's probably been 3+ years since that's happened. The sunroof replacement panel needs to come out sometime, but it won't happen before this weekend. I need to get the last of the plastidip off, then repaint and seal it. I didn't do a great job last time. Pretty much ready for TDE this weekend at Cresson. Gonna be warm out there, but the coolshirt is ready to go.
  8. I saw some reviews on that. I think I can get another weekend out of my RE71s, and I'm looking for a set to have as backups so I can throw them on when I see cords, hopefully for the September TDE event. I may wait and see if anything goes on sale around the 4th. I think I'd be fine with an RS4 or RC1.
  9. Sorry to bring this thread back from the dead, but there seems to be knowledge that's relevant to my situation. I'm planning on grabbing a set of RC1s for my E36 M3, but wanted to check on sizes. My wheels are 17x8.5 Kosei K1s, and I wanted to get the 235/40-17 tires. I don't see those in stock anywhere, so I was thinking about just stepping up to the 255/40-17. That's on the wide side for a 8.5" wheel, but it seems like it should work just fine. Does this sound right? I was planning on ordering direct from Maxxis, unless there are some other good ideas.
  10. Since I'm towing the car for at least the rest of the year, I'll probably try to grab a set of RC1s. I haven't found the size I want in stock anywhere (235/40-17). In someone elses video, it looked like I had no brake lights. I checked those, and everything works, I guess the old lights just aren't as bright as new LEDs (shocking). I found the risers for the rear wing in a box, so I'll try to get those thrown in this weekend. I'm sure there is no aerodynamic benefit to it at all, but I like the way it looks so I'm doing it. It could use a nut/bolt check to make sure everything is solid. Other than that, washing it is the only thing on my list. I spent a little more time looking at data. @Dave sent me some data from one of his fast laps for me to compare. The consistent theme is I brake too early it seems. Braking force (looking at G's) is pretty close. Mid corner speed and lateral acceleration are close in most areas, but I can see myself overslowing in a few places. I brake earlier, slow too much, get back on the gas a bit mid corner, then hold maintenance before hitting the power out. I think not overslowing would be a good place to work on for now. I was way off on my theoretical best lap too. I made some mistakes on my lap selection, so the data was bad. Data now shows a 1:23.15 for a theoretical best, so plenty of room for improvement. Driving cars is fun and I wish I could do more of it.
  11. I can get at least one more weekend out of these tires for sure, hopefully a bit more. I'll likely try RS4s or RC1s next. The prices for those seem pretty darn close unless one of them goes on sale soon. If I decide to plan ahead (for once) I'll bring the new set of something with me and just roll with the RE71s until I see cord. Not related to the knock back issue, but I've wondered about this. I've never replaced the hubs on this while I've had it. It doesn't seem to be a common issue on these cars as far as I can tell, but I know I'll need to do it someday. When I pull the wheels to clean and inspect, I'll poke around on the hubs to see how they feel.
  12. Is the frame shifting left and right the image stabilization at work, or is the mount actually moving?
  13. Been pretty busy, not not much has changed with the car. Got the coolshirt system rewired before the TDE event last weekend. It was hot, so that was definitely nice to have. The car did well, no issues at all. I still feel like I'm getting a little bit of pad knockback or something. The first press of the brake will be a but soft sometimes. I got in the habbit of giving it a little tap before the faster brake zones, and didn't have any issues. I took about 2 seconds off of my best time from the event in April. I looked at the data a bit last night, and my fast lap (1:24.84 via AIM Solo) was all my best sectors, until the very last one. I somehow lost 2/10ths in the rattlesnake exit to the start/finish timing loop. That seems like a whole lot of time for that turn. According to the data, the previous lap to my best had the best final sector. Tires have been my big concern, since I always went through them so quickly before. I have 3 days on these RE71Rs now, and they still have tread, so that's an improvement. They handle lots of slip pretty well. There was some decent drifting this weekend when I pushed too far, but it was still controllable. The shoulders look pretty good, but the inside half definitely has more tread left than the outside half. I'll try to get them flipped left-right before the next event. I did swap front to back wheels/tires Sunday morning. The fronts took a bit more of a beating than the rears. Are there secrets to driving fast while still maintaining tire life? If so, I should figure that out someday. As things stand now, I'm still renting a truck/trailer to tow it out. I should just get some slicks and send it. Might be fun. No real changes planned. I may try to pick up a different camera for in car. I've been borrowing a GoPro3, but I think it would be fun to have a forward and rear facing camera. I may grab some newer off brand camera for forward facing, and make the gopro rear. Something with a remote that I can stick on the dash. Once I'm belted in, I can't reach the buttons, so I end up burning 5-10 minutes of camera time just sitting at the grid.
  14. I like CW better. I think it's the more difficult config, and it is a bit slower which helps me with my relatively low power. I've spent a lot more time on the CW config compared to CCW though. Most of my CCW time has been running the full 3.1 mile track. Consequently, I'm not very good at wagon wheel CCW since I usually drive right by it.
