I am going to swap out the stock wheels on my 2004 GT3 to a set of Volk TE37's. The offsets are different though so I believe I am going to have to run spacers on the front:

From my understanding Stock GT3 wheels are:

Front: 8.5J X 18 offset 40 mm
Rear: 11J X 18 offset 63 mm


The Volks will be:

FRONTS
- Size: 18 x 8.5
- Wheel weight: 18 lbs
- Lug pattern: 5 x 130
- Offset: +49
- PCD: 130 (R14)
- Tires: 245/35/R18 - Michelin Pilot Sport Cup

REARS
- Size: 18 x 11.0
- Wheel weight: 20 lbs
- Lug pattern: 5 x 130
- Offset: +59
- PCD: 130 (R14)
- Tires: 295/30/R18 - Michelin Pilot Sport Cups

Which will mean my front wheels will be pulled in 9mm more, but the rears will be pushed out 4mm.


I know H&R makes good quality spacers, and they have a 14mm spacer available I can put on the fronts.

Which would make the front offset +35, while the rear would stay +59. A Difference of -5mm front, and -4mm rear, from the stock wheels. Giving me a 1mm wider track up front, compared to stock.

Does that all sound right? Would you guys recommend a different brand or spacers setup?

For reference, I plan to run Nitto NT01 in 245's up front and 315's rear once the Michelins are burned up.


Thanks

I believe you'll need a lot of camber up front to run +35 & 245 tires. Someone here probably knows for sure. Just be cautious that if you run -3 degrees camber in the front that you will probably eat street tires.

Right, that may be an issue.

I wish someone made 10mm spacers, it looks like it's all either 7mm or 14mm.

I may end up having to run 235's instead.

Go for the 7mm spacer and stay with the 245s at the front.
You're ok at the back at 59mm.
