I've been noticing the AutoX thread lately and just noticed there was no official Track / HPDE threads, mostly threads from MikeJ that get a lot of attention. So I think this should be the official Track / HPDE talk and chat thread.

I'll attempt to post up any links I find here that relate to this thread so they're easily found.

Good Thread with a little chat and good recommendations.

Next I'll give a little info about myself and it would be cool if we could copy the AutoX thread and get little introductions on people.

Name: Alex
Cars: 2009 Civic Si (Just a progress sway bar on it), 1998 BMW M3 Sedan (Track Rat)
Info: This will be my second track season and will be my first with the Civic, last year I had the pleasure to drive at New Hampshire International Speedway, and Watkins Glen, in a number of different e36's.

So who are the other track rats on the forum?

235 40 17 595 rsr on a 7.5 rim... tires are so fat on these rims but they worked really well



that 225/45/17 on the x8 rim looks right


didnt know the red si and scm had that much power..

i honestly don't care for laptimes to compare myself to anyone (vice versa). its more of a means of improvement.

btw i agree that bcn+ for the si's ride like ****... i seriously cant believe my bcn+ are 6 years old and have 120k on them lololol

thanks for the pics

i put 225/45 federals 595ss on x8 and it sits flush and i also put 235/40 on my fronts that are also x8 and they poke over the rim a tad. it looks good and wonder how they'll handle.


quick question for people with x9 in the fronts.

How much camber do you run fronts to fit 255/40 and offset of wheels

i want to run 17x9+35 with 255/40 but wonder if i need to bend my fender tabs. with about -2.5 camber front. i hope these will clear.

I have the same problem, but I think it's my spring moving. I heard the sound right after I changed my suspension. It creaks when I turn the wheel in any direction, if it is the steering rack do I take it to dealership?

Anybody have problem running x8+35 in the rear with 234/40?

I rolled my fenders, and I rub against the bumper screw when suspension is full compressed (turn in driveways and hard turns)

255/40/17 Hankook V12 Evo.

I have a few washers where the fender bolts onto the chassis to give me some extra clearance. I'm running +17 to clear my Brembo calipers lol

I'll try to get some pictures later when I have time of the setup. I don't know how much I'm dropped, but I'm about one finger or so all the way around.

so 255 or 245 on a 17x9+22 in the fronts should be able to clear no problems? with anywhere around -3 camber or more (depending on height)

i just want to get x9 in the fronts without having to bend the tabs, i already lost the clip that holds the fender liner in the middle right above the center of the wheel, my advans took them out some how (running x8.5 +31 235/40 No Camber at the time) lol

u have to at least roll our bend the tabs

Do you guys think a 17x9 +35 with 255/40 fit with only -1.5 camber, or does it really need -2 to -3? How about strut clearance?
it worked fine for me.. with -3camber

I don't think 1.5 will be able to clear, but I don't know I haven't tried, but it depends on your ride height as well. I'm sure it will be able to clear coilover strut not sure if you use oem. -3 kills tires for DD lol
been on -3.5 camber for over a year and its fine as long as you road race at least once a month

x9 +35 with 255's is do-able, but you're cutting it close to the strut.

Camber doesn't kill tires, toe does. Camber just causes uneven wear, but if you drive hard enough where you use the -3 camber, then it shouldn't be too much of a problem.
THIS


With major camber wear on one side, say you run staggered, and cannot rotate, you go thought tires very quickly. It wouldn't kill I guess I used the wrong term but you go through tires defiantly faster.
you can flip there tires
Un mount them and flip the sides

You'll go through front tires faster but if you think about it it'd be like for every 2 pairs of front you buy a set of rear rather than front and rear at the same time. Or so I see it that way.


Sent from my Autoguide iPhone app
225 used to last me 3-4 events
now 255 last 7 with 30%left

If you're worried about tire wear with that much camber, use stock wheels for dd without much camber then buy a set of dedicated wheels and adjust camber while you switch wheels. You can align the camber on both sides with a level, or even a leveling app on the iPhone. As long as you don't touch the tie rods you should be fine for toe, from what I believe. I'm not sure about faster, but I don't even think faster is adjustable on these cars anyways.

You won't see camber wear with dedicated track wheels obviously because you want the tire to be flat/on its maximum contact patch during a corner anyways, although perfectly level isn't attainable during all corners and changes within a corner, but you know what I mean.
as you change camber , toe changes


For the guys running 255s, what's your MPG like? Mine is like 24-25 MPG 80/20% (city/hwy) driving.

I used to get 28-30 MPG when I had my stock rims =/
29-30 combined

34 if 85% freeway
