Rim Offset and Tyre Fitment Guide
 

Ok, In addition to the "anything about rims" thread, this one is dedicated solely to rim offset and tyre fitment.

Below is what is meant by "offset". You can see how offset affects clearance from both the strut and gaurds.

Googling "offset calculator" will probably lead you to websites telling you how you can pay less interest on your mortgage... So go here instead.

Standard rim offsets are:
MY94-97 +55mm offset

MY98-00 +53mm offset

MY02-04 STi +53mm offset

MY01-05 +55mm offset

MY06-07 STi +53mm offset

Forester XT +48mm offset


Post pics of your rims (on your car) and state the rim size, and offset, as well as the tyre size. Along with any other info that may help people choose rim size and styles.

I'd say this is about the perfect fitment and size for looks AND practicality.. If they were wider or offset further, I'd probably have to rely on some tyre stretch to get me by without rubbing, and this of course compromises grip.

I don't get any rubbing now, except for a slight amount on full lock in the front (on the plastic guard liners, not the guards), and none at all in the rear even with a loaded car.

how is your rear tyre side wall, are the guards slicing onto it?

[QUOTE=Rexxar;741341]how is your rear tyre side wall, are the guards slicing onto it?[/QUOTE]

They were before I got the coilovers lifted, seems to be fine now...well until I can get them rolled and camber...


Sent from my iPhone using Tapatalk

im not the only one lol yeah get the guards pumped out using mallet and heat gun and bulk camber

For those in the 'stance' seen..

my current set up.

• STD R5 Coilovers (Front and rear Height, Damper and camber adjustable)
• XXR 521 18x8.5+35 in Flat Black
• Adrenza 215/35R18 Tyres - Stretched
• All Guards Rolled Flat
• Adjusted and wheel aligned
Lowered as much as possible without scraping, 2.5 degree’s camber all around.

Obviously it's not the most practical setup, but looks awesome in my opinion!

Yes they will clear brembos

Will look mint but will require all the guards rolled.

Depending how low you go, camber too.

Good luck

are you sure my 530's required 3 mil spacers

Awesome in the middle of selling
The Rex for a pig nose sti wanted to be sure
My wheels still fit,
Thanks guys

just double double check my xxr 530 had the same specs as yours and i purchased them off a guy who has an 06 sti and it needs spacers, the 527's may be slightly different but

i got 527 17x8.25 35+ on my gc which clears brembos without spacers 8.75 would surely fit

....

Cheers for the info guys really helpful,

Deal fell through with seller anyway waste of time, so I'll tackle this subject when the rex goes and find another pignose sti on the market haha, regards to spacers I think I'm running 3mm on the rex but worse comes to worse just get some off crawler haha,
thanks guys
