I would like to change the wheels on my 2007 Cayman S (1700 miles) to the Victor Equipment Lemans wheels for the black wheel "look". Since my current tires only have 1700 miles on the I would like to have them mounted on the new wheels, and also transfer the TPMS Sensors to the new wheels.

My current wheels are:

Sportdesign:
Front: 8 x 19 (57mm offset) w/ Potenza RE050A 235/35 ZR19
Rear: 9.5 x 19 (46mm offset) w/ Potenza RE050A 265/35 ZR19

I would like to get:

Victor Equipment Lemans
Front: 8 x 19 (45mm offset)
Rear: 9.5 x 19 (49mm offset)

My dealer tells me there is no problem with the front wheels, but using the 9.5 x 19 on the rear will hit the shock tower and suggested the Lemans 11 x 19 wheel. This would require 2 new tires which is what I am trying to avoid.

I am not real savvy on wheels and offsets and such, but I had an idea that if I added a spacer to the rear wheels I might be able to use the 9.5 x 19 and use my current rear tires. Is this possible, and if so, what size spacer should I use on the rear? Any other suggestions or advice would be greatly appreciated.

If those are the correct offsets for the Victor wheel, it will definitely fit. It only goes in another 3mm, the wheels I am using are 10'' rears that went in 10mm towards the shock tower without touching. Perhaps the dealer has 11'' readily in stock and not the 9.5's? I really suggest you dont' use 11'' rears if avoidable, because going to a 295 tire is more expensive and leads to understeer.

+1. With the specs you listed, wheels should fit. however, you might want to consider spacers on the rear to match the increased width you will be getting in the front.
