Aftermarket wheel offset???????? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

"My wheels specs:
Fronts 18x8 5-130 ET49
Rears 18x9.5 5-130 ET43
With these specs, no need for spacers..."

I just found some SSR GT3 wheels for sale. They are all 18x8, not staggered. The offset is ET49 on all of them.

Do you know if these will fit a 99 Boxster? The owner thinks they will fit newer Boxsters, but not a 1999...

Are you sure those are made for Porsche fitment? SSR made those wheels in non Porsche application too (ie. Nissan/BMW), so you should double check. Porsche wheels are normally staggered from front to back, with the wider wheel in the back.

Also, make sure the bolt pattern is 5-130.

Not sure if they were made for Porsches or not. The guy has them advertised as for a Boxster. I figured that since they are 8" wide, they would work. The bolt pattern is 5x130. Thanks.

No prob. It might fit, but I'm not sure you'd like the look or handling of all 4 wheels the same size. If you notice in my pic in a previous post, the wider rears have a fat lip, whereas the front wheels have a smaller lip. My fronts are 8in with a 49 offset so it seems you have located two sets of fronts.
