I am ready to purchase a new set of rims for my 996tt the fronts are 19x8.5 +45 offset and the rears are 19x11.5 +58 offset . Will these rims work on my car w/o any mods or spacers. Thanks in advance

 

I think stock twists are front et 50 and rear et 40 or 45 so it sounds like spacers would be needed.

 

Fronts are pretty far out for a 996TT, but will be OK if the tire isn't too wide. I doubt 245's will work but 235 should be OK. You may have to roll the fender lips.

The rears are OK if you add a 15mm spacer and bolts. They won't work without them. I have the spacers ($96 a pair) and the bolts $6 each) if you need them.

 

One of the best sites I've found to help me understand and fit wheels and tires is 1010 tires. Here's the link to their site that has very helpfull information:

Very general information and not vehicle specific, certainly not as much as we have here.

 

Thanks Damon, never looked at your site for this type of info. Just like the Wheel Offset and Tire Size calculator on the 1010 site. Both sites are very helpful IMHO!

Cheers!
