R-Compounds for STi
�
�
Well i got myself a sponsor for this AutoX season :banana: and plan to spend the $$$ on a set of R-compounds.
The big question is which ones?
I know Hoosiers are the fastest in terms of grip & wear but I only got enough money to get the magnetic decals and one set of tires.
The Kumho Victoracers are not availible in 245/40/17 (I was thinking this size would be best on the stock STi)
I heard some poor reviews with the V700's on the STi
Anyone care to shed a little light?

I've been using victoracers to dial in my STi... no problems here.
255/40-17

Looking at your progress in the NERDS Sliderule cup so far says that setup is doing you quite well ;)

Size doesnt exist there are 245/45/17s I would go with the 255/40/17s on the stock wheel.

255/40-17[/B][/QUOTE]
I've asked this before but I still wonder about the result. You're running in AS so you're using a 7.5" wheel, which might be part of it. I talked to Tire Rack and they were quite insisitent that 255/40 Victoracers would not fit without fender flaring. I'm racing in ESP so I got the SSR 17x8.5 ET48 wheels with 245/40 shaved Ecstas. I'm running the stock struts with pink springs. On the rear there is less than a half inch between the tire and the strut. That's with -1.7 degrees camber in the rear. The fronts seem to have plenty of room. Looking at the tires I have and seeing that the specification for section width on the Victoracer is a lot wider than the Ecsta, it seems that Tire Rack would be correct and they would not fit.
Any ideas? Less wheel (the offset would seem to help equalize that if you're running the stock ET53 offset), more offset, less camber, or just fits? It would be great to run the Victoracers. I've been running the 235/40 Toyo RA-1s on 17x7.5 Rotas and I do great locally but the Evo with 255/40 Victos beat me in Utah. Note that the RA-1s were only because the SSR wheels were delayed for 3 months so I had to run what I had.

The 255s will fit on the stock wheels without fender rolling. On a 48 offset wheel you will have to roll the fender. The 5mms matter.

I believe the 48 vs. 53 is actually helping, but of course the extra total inch doesn't. So the net effect is almost 8mm closer to the strut. I think the net result with the wider wheel would probably be better if it weren't for the Victoracer only being available in limited sizes. Here's hoping the new V710 will come in a favorable set of sizes...

And be safe/legal.
I think the best set up without whipping out the sawsall for esp will be some 8-8.5 inch et+48 rims rolled fenders and 265s

hmm...Good points I didn't even think about the Rota tarmac II's that I will be using are ET48.
So I'm back to the drawing board :(

a non-scientific test:
i showed up at a test and tune autocross thingy. there was an identical STi there. we were both on stock rubber. it was a 45 second track. i beat him by a full second.
the very next week, i show up w/ victoracers 245's and he shows up w/ the new fancy hoosiers 225's. he beats me by a full second.
so my non-scientific result is that the hoosiers are 2 seconds quicker on a 45 second course.
variables: i was sick and dizzy the second weekend. i was originally faster the second weekend, but he steadily improved to beat my best time by over a second.

I think i am gonna roll the dice and spring for the hoosiers... If they cord before the season ends...well back to street tires till next year :lol:

I'm running mine on SSR GT7s ... I'm 90% certain they have a 48 offset. Still plenty of room on the outside. No rolling required! The 275s should fit with some fender rolling... just can't fit them in stock.

255's on stock 7.5" wheels? It may "fit", but its surely not optimal. You're probably wasting a lot of tread squeezing it on there.
275's, eh? good luck with that one pal. :lol: I don't know what your definition of "fit" is, but apparently it dosn't involve actually moving the car with them on. :lol:

You gotta do what you can in stock class... Any little bit extra I can get, I'll take. National Championships have been won and lost over less...

No luck involved... Though it was a NIGHTMARE to mount on the stock wheel. Moving the car afterwards wasn't a problem as they didn't rub on moving the car around normally (with 5mm spacers w the stock wheels). The problem was when the the wheel would move in bump the VERY out side of the tire would hit the inside fender lip. If I could roll the lip in A-Stock I would be using 275s...
I WILL be ditching the 255 kumhos in favor of the the 245 Hoosiers for Topeka and possibly some national tours if I can get enough cash together.

Mounting them on the car and looking like they won't rub and using them in competition are two different animals. Thats a radical tire that i'm sure will rub somewhere. Holding 1+ G's in a corner with those wide meats (almost 11" wide) is going to scrub something. Especially on stock suspension. The rear fender liner is a very suspect item. Front has more clearance though. On my wrx (which has the exact same wheelhouse as an STi, RS or any other GD variant) has lightly rubbed 235 Bridgestone wide street tires on full bump in the rear. I've seen it happen on fronts as well (those ghost scruffs that appear on the sidewall and you know your not rolling over). I have over 2* neg camber (f&r) on 17x8, +45 offset (a little less than stock sti BBS). Its rare when it will rub, but it has happened. Unless your suspension is so hard and immovable, it bangs over cigarette butts in the road, 275's are not very realistic an application.
Besides, here is what a 275 looks like stuffed on a stock wheel:

But 275s may be doable on an esp car with just fender rolling.
Oh and the 05s are comming the the fenders rolled(or just removed cant tell yet) and 8 inch rims. Along with a supposably better spring sturt set up and new rear suspension. So it unfortunately looks like the 04s will be at a disadvantage in AS soon.

But that's why I'm NOT running them, and stuck with the 255s which don't rub at all. You could fit them on an ESP car though... no doubt about it in my mind.

Surprisingly the 275 was not nearly as "bowed" as I expected it to be on the stock wheel. It had a very severe cantilivered effect on the side wall as shown below... Please note, I'm not and artist just trying to illustrate the "idea"

JUST an FYI Im running a 235/45/17 this is 25.8 in diam. kumho MX on tarmac 2's have my ride hieght set at 13.5 and I'm rubbing. Tried to roll my fender a bit at home but need to take it to a body shop to get it perfect.
| afpdl | 04-30-2004 01:42 AM |
Baseball bat+ heat gun + an hour = 245/45/17 victos on sdrs with 13.5 inch ride height. And with the right wheel, camber set up 275s.
