I'm thinking about buying a older Boxster as a daily driver. I have a set of Champion Motorsports RG5's laying around.

The fronts are 19x8.5 and the rears are 19x11. The tires are: 235/35-19 front & 275/30-19 rear. I believe the front offset is 53mm and the rears are about 60-64mm. I could be a little off on the measurements, but close.

They fit my NB 993.

Will these fit a Boxster?

 

I don't know for sure, but I'm guessing they'll be too wide. I think the Techart Formulas for the Boxster are about as big as you can go. You might want to check their specs.

Also, I think the Wheel Dynamics website lists the most extreme fitment a Boxster can take.

 

i believe they will fit... May need to roll the rear fenders though and not sure about offsets...

 

They will hit the strut. You need to be closer to a 40 offset, and even that is very close to the strut.

 

I would call Champion Motorsports 1-800.775.2456 they should be able to tell you.

 

i used to run 19s on my 986. the fronts were 19x8.5 45mm offset and the rears 19x10.5 45mm, with 225 & 275 tires. the wheels were fairly flush to the edge of the fender. i think you may need a small 5mm spacer for the front. your rear is 0.5" wider which is 0.25" (6mm) per side wider. so with a spacer (20 mm), your offset will be about 45mm but the wheel will stick out 6mm than my setup. if you go with a smaller spacer, you may hit the strut tower. (unfortuanetly i didn't check how close my wheel was to the strut tower.) my guess, they won't fit and look cool.
