Hi. I wanna know if this set Maxxim by Konig 17 x 7 +42 and Maxxis RC1 225/45 with Eibach's springs will be fine. Is just for autocross championship.

Thanks!

They will fit fine, but aren't 225s a bit wide on a 7" rim? Most guys run 195 or 205 to maintain a better contact patch. Or is there a class restriction?

There is no stock in other size :(

According to the Maxxis website, 225/45 is for 7" to 8" rim. 7.5" is the best fit.

Here, in Perú, there is not many options in slicks or semislicks tires :(. Really i want the Toyo R888R in 215/45/16, but i have to import from USA and the shipping to here is very expensive :/

Thanks!

If you are autocrossing, you want RE-71s in either 195s or 205s for a 7" rim. Those Maxxis are really track tires and are too wide to be competitive on a 7" rim. I would think that they won't work well in an autox situation. If you are only doing short runs the tires won't stay hot and won't work as well as they would on the track where the tires can stay at proper running temperatures.
225s are way too wide. 7" rims will wallow around in them, the sidewalls will roll in hard cornering and the contact patch will be distorted and not a large as it could be. Lots of lost time and not really competitive.

The problem is that I have a 17x7 wheel set just for autox (for daily, i use the 18 '' stock).

In the last autocross date, I ran with the Hankook Ventus Z214 (TW 40) 205/50/16 and it was amazing! But this tire is penalized with 2.3 seconds per round. (Penalties: TW 99 to 61 = 0.5 sec per round. TW 60 to 0 = 2.3 sec per round).For that, im looking for tires with TW 100 or close to that. The Maxxis are TW 100 and are cheap ($ 150 per unit).

Is complicated when the domestic market are limited. For example: The RE-71 do not sell it here.

Other option are the Federal 595 RSR and 595 RS-RR

Some pics with the Hankook Z214.





Thanks again!

:dunno:Well, it sounds like whichever way you go with the choices at hand you are going to lose a second or so, either from being penalized or from crappy tire choices.:dunno:

What do you think about the Federal 595 RSR or RS-RR 215/45/17?

Cheap tires, some like them some don't. They don't seem to last long. There are some reports of tread separation and belt failure. They might be good for a day or two on the track if nothing else is is available but other than that.....:dunno:
215 is still too wide for a 7" rim, at least if you want to be even a bit competitive.

Damn :|

What about a wheel set 17x8 +53 (STI original wheel forged)?

The 215s on a 8" rims is a lot better. +53 offset will give you a narrower track and a bit less directional stability. Thats not a bad thing as the car will respond to rapid steering inputs that much faster. Just make sure you measure carefully for backset. You don't want the wheel to hit the shock.

Sh*t, i'm on a dilemma. I don't know what wheel set is better option, Konig 17x7 +42 or BBS forged 17x8 +53.

Is just for autocross.

Thanks Arathol!
