400rwhp vs traction vs tires size
Hi all,
I have a 13B-RE powered FC with a TO4R. I read on the board that people with big turbo setup have no traction in 1-2-3 gears with 275-285 tires. In my case the car is only spinning when I shift from 1st to 2nd gear. I'm playing with the clutch. I have 255 kumho MX tires on the rear and Tein flex coilover. So I think that maybe I don't have the power I should have or the tire/suspension setup are very good. There is no dyno near where I am.
I would like to know how is your traction, what kind of power you are putting to the ground and what is your suspension/tire (tire size and make) setup.
Thanks!
Alex

bottom line is low-pro tires are for turning, hi-pro let the sidewalls bend ad your contact patch gets bigger when you're driving in a straight line.
the good news is 15" rims are cheap. slap on a set of drag tires and run those when you go to the track.

Depends on how you drive. If you granny shift every gear you shouldn't break lose but if you power shift 1st-2nd or 2nd-3rd you will break lose. I did plenty on my old FD running 275s in the rear.

High HP rotaries typically dont have the traction issues of other cars because they do not make that much TQ. And wider tires do not help straight line traction that much. A wide contact patch is good for turning while a long contact patch is what gives you straight line traction, IE a taller tire

well its cooler around here in ct now around 65-70 during the day. in second gear when the 2nd turbo comes online i spin the tires. also first to second shift is pretty harry as well. i am only making 360 rwhp. i have koni shocks with eibach springs, and newish 245 toyo proxes t1-s. kind of sucks actually.

which brings us to the other half of the equation: suspension setup

kumho mx are pretty decent tires.
i've got 245-45-17 kumho 712's. they're better than i thought they'd be, but i'll still light up first and second...and third if i shift too hard.
rsr race springs, koni rear, tokico front, toe links and trailing arms

I have Fuzion ZRi 245/45/16 on the stock wheels, and I have the stock suspension. On pump gas (450 whp @ 17psi) I spin all of first, most of second, and chrip them in third. When I had race gas in it (503whp @ 22psi) I didn't have traction until top of 3rd gear........... I need wider wheels.

i think i'm just gonna grab some mickey thompson 255/50's and stick them on the spare rims for when i want straight line traction.
ryan1, i've heard almost nothing but good things about the mx tires, so i was thinking about getting a set when i get the new wheels. so other than the sharpness and initial response, how was the overall handling compared to the 712's? should i not waste the money on them?

PDViper77, I work at a shop that sells fusion tires. They are junk, don't waste your $$ on them again for your new rims.
GUITARJUNKIE28, I do like them and think are worth the $$. I think overall they handle better than the 712s. I eqaute the difference between the 712 and the mx, to the first few runs you ever made on slicks. Once your used to the difference it's fine. I think that once I put the mx's on my 9.5" rims instead of 8.5" it will help to sharpen them up.
