whats the widest i can go front and rear for my 89 t2, also how big can i go and still be functional??

rxchx7 11-21-2002 03:15 PM

i was looking at racing hart cp-035 or cp-035r and wasn't sure if i should go up to 18" b/c the cp-035r only come in 18"

Rob x-7 11-21-2002 04:25 PM

18" look nice but can be a bit overkill depending on the rim and if your car is lowered or not

Go for the Gold man!!

Volk TE37 Drag Wheels, 13x8!!! $2400CDN!!

Pimpin' from the side, But holy wide!! https://www.nopistons.com/forums/pub...#>/biggrin.png

im not sure exactly how wide my wheels are but the tire size 245/35/17..........they are so wide in the front the only thing I can stick between the rim and spring is literaly a piece of paper. never ever rubs tho!!

cymfc3s 11-22-2002 04:31 PM

18x9.5 is pimp. But its a super tight fit.

vosko 11-22-2002 06:19 PM

17's will look just as good too.... 18's are more bling bling though...

mazdaspeed101 11-22-2002 07:24 PM

I heard that bigger rims slow you down abit.

Jerk_Racer 11-22-2002 08:29 PM

You bet they slow you down. With no money left in your wallet after buying a set of exotic lightweight 18's you can't afford to buy gas. https://www.nopistons.com/forums/pub...DIR#>/wink.png



17x8 and 17x9 (offset +35 if I'm not mistaken - let me know) are mighty sweet and don't make your stock brakes look too puny by comparison. Ever see an old H-badged car with 18's? The rear drum brakes aren't much larger than a fist. Awfully lame. If you must get 18's, please for the sake of the Domokun, get a big brake upgrade.

rxchx7 11-28-2002 12:10 PM

i didn't get a big brake kit but i did get cross drilled and slotted brembros with hawk pads. I'm going to get the ss braided brake lines soon. How much can i drop it w/ 17s and w/18s, b/c I only wanted to drop it an inch or so?

Jerk_Racer 11-29-2002 04:11 AM

Dude, the wheel diameter does not dictate how much you can drop it. Overall tire diameter does. The difference from 235/45R18 to a 275/60R18 is a crazy example. Both are 17's but guess which one might fit.



BTW, those Harts wheels aren't the best for the street. A decent hit and they'll be garbage.

Erik 11-29-2002 07:22 AM

also, if you wanna fit anything wider than a 7 or maybe 7.5 inch rim up front you'll need a different offset besides the stock +40mm...like 38. 225 tires will fit but barely (up front)...wider than that and you'll need a different offset.

Dragon 11-29-2002 07:30 AM

I've got 10J 45mm offset on the rear of my FD.. I've seen FC's running around with 10 and 10.5J rims on the rear over here in Japan, not sure what offset they are using...

Jerk_Racer 11-29-2002 11:29 AM

Well, Dragon, this is your homework assignment: Find that out! See what offsets and what they did to squeeze them in. i.e. rolled fenders, pulled fenders or blister fenders.

Dragon 11-29-2002 12:36 PM

https://www.nopistons.com/forums/pub...#>/biggrin.png I own a fender roller that bolts to the hub and will get you a extra 1J easy...

RETed 11-29-2002 07:58 PM

Boy, I'd like to see you roll the FC3S rears!&nbsp They are double thick, so it takes a lot of muscle to make them budge!



Usually, 8" wide up front on 225 wide and 9" in rear on 245 or 255 wide tires.&nbsp This is the typical "safe" set-up for the FC under stock fenders.



If you are going blister kit, you can go 9" up front and 10" in rear.&nbsp Tires would be 255 up front and 285 in rear.
