Experts:

I am putting my RPF1s back on my 11 WRX soon. The wheels are 18x9.5 +38 with 265/35 tires on. However I have 11 STi brembos on and the wheels require a 10mm spacer up front to clear.

My plan:

Install ARP Extended studs and a 10mm slip on spacer up front to clear the Brembos.

My question:

This will make the rears 18x9.5 +38 and the fronts 18x9.5 +28 all with the 265/35 tire.

I have heard rumors that staggered offsets are bad, but fine if done correctly. Will this be okay?

Thank you all

I think it's more about tire specs than anything. You have to keep those the same so the rotations are the same rolling/outside diameter. But that's just from my brain. I'd talk to someone like AI and see what they have to say.

Or wheeldude or speed element. Those guys run all kinds of different set ups.

 

I guess you'd lose the ability to rotate the tires front to back? But can't of anything in particular otherwise.

 

As long as the wheels and tires are identical you should be fine. When I had my Grids I had to run a 5mm spacer in the front to clear my brembos. Ran them this way for almost 2 years with no issue.

I did end up adding 5mm spacers to the rear eventually though to even them out.

Any reason why you wouldn't just do ARP studs at all four corners and run spacers front and rear?

 

I have the 265/35 tire if I run 18x9.5 +28 all around they wont sit as nicely as they would at +38 and ill have to run a lot more camber than the -1.4 im running now in the rear.

 

This, generally staggered wheel setups are done with different size tires. As long as the overall diameter of the tires are all the same you are good to go. I ran spacers in the rear on my fxt to clear the struts no problem and many many people run spacers in the front for the very reason you are in order to clear the brembos.

 

So a 10mm difference front and rear should be okay? i know someone who is doing it on an STi and is fine so far

 

Should be fine yes.

 

Why wouldn't he be able to? It's spaced on the studs.


You should be fine Brendan, the car won't handle the same though with a 10mm difference IMHO. Run it all around as Matt suggested.

 

Yeah you're good bud. I know of a few guys that have actual wheels specs that are different. Same size front and rear but with different offsets and they have had zero problems.

 

Handling should still be fine honestly. If I remember correctly the wider track in front with help with turn-in and a few other things. (Not 100% sure, Karlton explained it to me once but that was a while ago)

But yes, ideally 10mm spacers with APR studs at all 4 corners would be the best option. If Huck can run 18x9.5 +38 with 275/35/18 tires on his stock body with minimal camber you should have no problem with the 265 and slightly lower offset. Just something to think about.

 

But too wide in comparison to the rear would hurt though.

 

Of course. In this case he will be fine.

 

But not when he #needzmoarlow


If this prevents you from dropping your frame or oil pan to the ground, avoid it.

 

yeah all that matters is the diameter, keep in mind every AWD lamborghini runs a staggered setup just fine
