Wheel Spacer Help
 

I recently put TSW Bathurst wheels on my 2015 Z, and while I'm having my rear brakes upgraded I wanted to throw on some spacers. The rear wheels are still tucked a bit with the stock TSW offset.

The TSW Bathurst specs are:

Front: 19x8.5 +15 (these sit nice and flush - perhaps a little on the 'aggressive' side)

Rear: 19x10.5 +27

I'm not lowered, and on the fence between 15mm or 20mm spacers.

Also, is it recommended to go with the extended stud spacers or just the bolt-on for the rears?

Thank you all for the help!

I'm running an 18x9 +18 on the front and an 18x10 +25 rear. 20mm spacer on the rear so a final +5. They sit an aggressive flush on a non lowered car. I didn't know if I should get a 15 or a 20 either, but I'm glad I got the 20. I've only had this car for a month, so my knowledge is limited at this point. My specs were pretty close to yours so I thought it might help. I can't give you a definitive answer as far as the spacer types go, but I'm running a set of bolt on H&R's.

2" staggered wheel difference would use about the same offset F/R,,,so your target for the rear is +15 (12mm spacer) or measure up-camber play's a big role...& so does tire size (if you're flushing the sidewalls or tread)

Thanks for letting me know about your experience. I'm .5 inch wider in the rear and running 305 tires. So just not sure if the 20mm might be too much...

Thanks so much -- I had thought about it this way. Like I said above, given that I have 305s on the rear, I think I might be better off with 15mm on the rear so I don't wind up looking like a 4x4...:eek:

However, I previously had Avant Garde M550s on this car, they were 19x11 +18, and sat really nice and flush on the rear with 305s. I would have to go with 20mm to approach a similar width on the rear to match those...

20mm fron and 25mm rear is what I have for mine
