Hey guys.. opinions on this por favor..

Here is my wheel offset
They are:
x9.5 ET38
x12 ET60

Front tires 265x35x20

Shouldn't the rear be a 325x30x21 not a 325x25??

Or will the 325x25 work?

tires are MP4S.

Thanks in advance

if you were R22...then 325/25 would work. R21 325/25 is down 3.5% compared to stock 315/30.

For the AWD and electronics, you need to maintain the front-to-rear rolling radius stagger ratio. So a 265/35R20 needs to be paired with a 325/30R21 rear. The 325/25R21 has a too small rolling radius.

I run front 235/35/20 20 x 9 1/2" with 40 offset
rear 325/30/21 21 x 12 1/2" with 70 offset

Why so narrow in front? Must understeer like hell...

Pad Bender

hvcone...You must be running 265 up front.

Any picks of the wheels and tires to get a sense of offsets?....I am planning on running a very similar setup.

I'm certain its a typo. He meant 265 up front not 235

SORRY these cell phones are tough to see when you're a hundred, yes thank you 265 in the front

Thanks for all the replies guys! This confirms what I interpreted from previous posts, just wanted to make sure.

Stock wheels 265/35/20, 325 /30 /21 fit fine even lowered on H&R springs

That makes more sense

I run the same tires: PSC2 N2 991.2 GT2/3RS spec, great street/track dual use tire

The base wheels are a bit narrow for these tires though. Being 0.5" wider, the Exclusive Design wheels are a better fit.

Pad Bender

Agree... 9.5 and 12.0 is better fit for 265/325 . PSC2 have a fatter sidewall compared to just about everything.
