You should beable to go 275. I went 265 to be safe as I'm doing coilovers and didn't want to modify wheel wells once slammed. My rear et 56 w/ 10mm spacer. Fronts et 47 w/ 235x35x19 Rear tire size265x30x19 Hope this helps.

Just purchased a set of 993 Turbo hollow spokes, ET40 rear, so we'll see how these fit. They currently have Turbo size tires on (225/40-18F, 285/30-18R) so I should have some good input on how wide you can go once I get these on the car.

I'm looking at a set of 996 TURBO wheels, would the offset fit my 00" S? The front seems to be fine but I'm worried about the rear, especially the 11" width?

Front 18x8 ET 50 with 225/40R18

Rear 18x11 ET 45 with 295/30R18

Thanks

Absolutely not. Short of doing fender flares, there is no way that you are going to fit an 11" wide wheel on a Boxster. By the way, as I used to have a set, the 993 Turbo Hollow Spokes come in either ET40 (Turbo or wide body fitment) or ET65 (narrow body fitment). I ran the 18x10 ET40 version, and while they fit, this is as wide as you can go. I am now running BBS RSII 18x10 ET45, and this is a perfect fit.

Thanks. Didn't think so neither. What size tyres are you running on those 18x10s?

I have a set of wheels (986 or 996 Twists...not sure):

17 x 7, 52mm offset (front) and
17 x 9, 55mm offset (rear)

with Toyo 888's. I used these on my 968. Will these work on my 2001 "S"?

Yup, those should work just fine. In my owners manual the standard offset for a 986 would be 50mm in front and 52mm in the rear.
