sweet! I stand corrected...

I max out my car on rocky road all the time, but I do less than 200 because of undersized tires. I'm thinking its somewhere around 170, but not sure. It's weird having to let off because you're bouncing off the red limiter in 5th lol.

I haven't had a chance to try it with the new starspecs though (slightly oversized) - i'll have to wait until sept. 6th

Were you running Dunlop * Specs at auto-x? That's what I am running too.. is it me or they really impressive tires? They're better in the *rain* than my old Kuhmo's in the dry!

What rear end's in there now?

sb_600 · 08-04-2010, 08:31 AM

yeah that's what i've got - 255/40R17 on all corners. I think they're awesome, although the only thing i can compare them to are kumho ecsta xs in a 205/50R15. I've heard they're almost comparable to an R888 too - everyone agrees that those are some of the best "cheater" street tires out there. In that size, i'm not worried about overheating them at the track either.

For the rear end, I'm not sure exactly but it's either a 3.91 or a 4.10 LSD.

For those who are interested, here are the videos of my fastest run in each configuration:

hehe, not really correct. My car is classified in D/Mod, this is Modified class = I can do pretty well anything I want with the car. Brakes are my least worries.
I run on stock calipers and Brembo blank rotors and Hawk HP+ for Auot-X and Hawk HT10 for the track. I have propper vents right up to the caliper plate, this makes a big difference. In the rear I also have just stock rotors and calipers and always have Hawk HT10 on.

I do not have any issues with braking, NEVER at Auto-X and also no problems on the track ... and I run a 2:25 flat at Calabogie

(allthough I dont get up to 200 on the back straight)

Friend of mine installed a BBK kit on his E30 a couple of years ago and had a hard time to find the propper braking balance, that BBK kit sure improved the braking on the track but he also locked up the front a lot.

Thanks for clearing this up Klaus. I guess we'll see what my balance is like. UUC spent a lot of time getting the internal dimensions of the front caliper correct so as to decrease pedal travel and keep balance the same.

I'm not sure why everyone jumped on this little tidbit so much anyway.. The *driver* (ME!) will be the weakest link of my car on the track or autox, no questions, and I said I *wasn't* installing the BBK lol.

I must have misread the points system, or read an old post about it. I understood that each improvement accumulates points, which moves you closer to a new class. Back then, between FI, ECU, coilovers and tire width I would have jumped to A. I know my car will be hopelessly uncompetitive; that's NOT why I drive or built this car.

I built it because I loved doing so, and I drive it because I love driving it. Nothing more. No glory or bragging rights. I'd be happiest with a giant abandoned airport all to myself and a timing system.

well said!

Im pretty sure brakes are open and dont count as a mod. I have HP+ in front and HPS back and it brakes pretty good. Klaus got any solution for the squealing of the HP+?

When you find said airport, let me know!

everlast · 08-05-2010, 11:28 AM

Just spent some time reading this years classification rules.. Boy, the document I read must have been read old; it's nothing like this. Anyway, from what I can tell I'd be Street Prep with 7 points. (4 for turbo, 3 for suspension modifications.) I'm gonna read more.

I said I wanted ALONE TIME at the airport.

True, clever!!

carjoe · 08-05-2010, 11:52 AM

There's an app for that...
I believe there was an airport in Embrun but I'm not sure it's accessible. 8)

You may have been reading MCO's classification system. They do it differently than SCCA or regionals to limit the number of classes (to 5) - E, D, C, B, and A.

15 prep points, and you bump up a class. For example, my e36 is a base D-class car, but with my 29 prep points, I'm at the top of C. If I do anything else, I get bumped to B. Like you, I started prepping my car to be the way I wanted it and counted the points after - I got lucky

There's a few things I'm holding out on right now because I do want to stay competive though, and it helps keep the budget in check too
