wheel spacers

[NoItIsNotACivic]

i have to get a set of wheel spacers and longer studs so i can fit a bigger rotor and wilwood caliper behind my rota GT3's which are 15x7. do i need to ad spacers all around or can i just doo the fronts?

What offset are your wheels?

Which BBK are you looking at?

[NoItIsNotACivic]

the rims are a 40 offset, and the bbk is a wilwood caliper matched with a generic rotor and pads from an ebay store (i know don't laugh, but what other option is there? k-sport?)

I AM ALSO DOING THE REAR DISC SWAP FROM THE 96 CELICA GTS. BUT I AM USING THE ROTORS PADS AND STEEL BRAIDED LINES FROM THE EBAY STORE TO MATCH THE FRONT, AND HAVING THE CELICA CALIPERS POWDERCOATED BLACK TO MATCH THE WILWOOD CALIPER UP FRONT

Is this by any chance the fast brakes kit with the 11" rotors?

If so, you shouldn't have any problems with clearance even on a 15" wheel that would require wheel spacers. I know a guy who was running the same Wilwood BBK on 15x7 +38 wheels and they fit without any modifications.

i hope that is how it works out, but i had the template from the guy and it seems that there is a tiny bit of interference with the caliper and the back of the wheel spokes. it seems to only need a 5mm spacer to have the clearance i need. bummer cause i have 195-55-15 and i was hoping on truying to shoehorn some 205 50's with out rubbing the fenders, but with spacers i dont know if i can.

if i do have to use spacers? do i only need them on the front or do i have to get them all the way around?

how did your friend like the brake kit?

That wouldn't happened to be Sean2Sean - would it?

As far as spacers go - depends on what you are after. Just pushing the wheels away for clearance only or getting clearance and adjusting the car's front/rear track?

i dont think we are talking about the same dude. this is Revolution Brake LLC.
wider track width would be nice but lets be serious. 5 mm on each side is not going to make a noticeable difference. the onlyconcern i have is if i can still put the 205 50's without fender rub.

the main question was, do i need to use spacers at all four corners? or just the front for clearance?

Depends on what the brand and type of tire you run.

Some 205/50/15 tires run wider than their specs suggestion, some have measured in reality 215 or 220mm wide. In that case you would have to roll and pull your fenders out a bit.

You can probably get away with the stock wheel studs if the spacers are only 5mm, just be sure to get at least 6.5-7 turns on the lug nuts to make sure they're nice and secure.

Yeah, I worded it incorrectly. I meant to say that there was a 8th gen Corolla owner that was running Wilwood caliper and a 11" rotor setup - his name was Sean2Sean. Actually had one setup specifically for the 8th gen, his car was a test case, given that some have expressed interest in a BBK. Unfortunately, demand wasn't there and I believe that "kit" has been discontinued. You can still have Wilwood custom make you a setup or pick up one from another vendor - like Revolution Brake.

As for the spacers - you have to measure the track of the car and see if the offset is appropriate. Example, if you add a 5mm spacer on just the front that has a front track 12mm wider than the rears, you would be running a total 22mm wider track at the front than the rear - almost an 1" wider in the front than the rear.

Might ask so what? Adjustments in front and rear track can have a great influence on handling of the car - both good and bad. Along with them, tire choice, wheel, suspension settings, spring rates, strut damping, etc. - all play a very crucial role in handling. Even a 5mm spacer can make a poor running car, handle great or a decent handling car yield spooky steering behavior. Not only in low speeds, nearly static cases, but under acceleration, hard braking, and cornering.

Personally, I'd apply the same offset all around to keep the ratios of the tracks pretty close. Like PR mentioned, a 5mm spacer should not be a big deal on OEM studs. Past that - be safer to run longer studs. A 205 width tire is hit or miss for clearing the fender - depends on how much of a drop you will end up with in the end. For my 2002 - running one of the narrower 205/45-16 tires (+38mm offset), no camber adjustment, on KYB-GR2 on TRD springs (~1"-1.5" drop) it would just rub the rear fenders on bigger bumps. Fronts were fine - only rubbed on steering lock.
