255 in the front u serious? U need 245 at front. 285 is fine in rear, but first are u dropped? Those offsets should be fine without spacers. Some member are running 38/42 without spacers

 

I'm dropped by about an inch.

 

i would run the same size tires as i have. 245/35 f 275 30 rear, i have a 32 offset in front.

 

W +38 u need a 6mm spacer at least to clear if i were u i would run a 15mm hubcentric spacer and sit at 23/42 that should look ok!!! Depending on drop though i doubt a 255/35 would clear! U will def want to raise it! Unles u go 245/35 u should be ok! Def front needs to be spaced out though. Don't run flat spacers u need at least a 6mm for clearance so i recommend a 15mm spacer w a 245/35 and don't slam so low on front.

 

CV1 +38 have caliper clearance issues , u need at least a 6mm spacer to clear or u gonna hit caliper! But then again u need Hubcentric to eliminate vibrating issues.

 

Thanks for the help guys. Would it be a problem running 245/35/20 with 285/30/20 in the back? According to the wheel calculator, at 60mph, the front would read 59.6 and rear would read 60.1mph. Would the 0.5mph difference trip the vdc/abs?

 

That set-up I's the proper size to run actually , that's what vossen recomends so u have proper speedometer readings. This I's the best most practical comfortable set-up.

 

Vossen also offers Akata 6mm spacers that u can run on Front to be at a +32 ! Look into that also if u want the 255/35 but on a 9.0 front def stick to 245/35z

 

Sounds good. I'll switch to 245s and slap on some 10mm spacers.

Do you think I can run any spacer in the back with 285s? Just dont want the rear to look too tucked in or uneven compared to the front.

 

U can run 10mm spacers but u need to install the extended studs because 10 won't let the stock studs fit the lugs! They not long enough and even if u get spacers w extended studs your stock studs will hit back of rim and will need stock studs to be shaved down .

Make sense? Hope this I's clear.

 

If i were u honestly for all the concerns! Just hit up Jav at Vossen up for some Akata 6mm spacers on front and rear and sit at 32/36 offsets! That will look good.

 

Yeah, I understand the spacers. Even if i got the 6mm ones, i would not feel comfortable without extending the studs. So i'm planning to get teh eibach pro 10mm with extended studs. I figured if i could install my own turboes, i can change out the studs.

 

I just wished i found out about the caliper clearance problem before i bought the 38 offsets.

Does everyone with 38 offset have problems with sport brakes? Did anyone not have the problem.

 

Then u set man! Def go 10 then that's gonna look sweet .

 

It was the first batch of CV1s that had this issue! Maby u can contact Vossen to see if they will swap out the front to a +32 ! they have 5 year workmanship warranty ! It's worth a shot .
