You are right Drjim! The OP's OZ wheels are 20"s. Tire Rack's 20" OZ wheel fitment 8.5 & 11 x 20" shows 55mm front and 50mm rear offset (confirmed w/call to TR) vs. stock 61mm F & 50mmR. The front wheels will be pushed outboard marginally (6mm) from stock.
My GT4 wont be in my driveway until March sometime. But the 19" R wheels look to be viable option. May require some minimal spacers?

There are numerous threads on wheel sizes and fitments as well as requirements to be met on here: 18", 19" and 20".
To summarize the requirements again:
1) toelink replacement
2) different offset
3) different width
4) change caliper
5) alignment
All of these are addressed in those thread in one form/combination or the other. Some of these even include pictures. Just because it isn't on the first page ..........

The OZs are 55 front and 50 rear. Will see how it all works out at full lean on track, but I expect it will be fine as tire rack used a GT4 to measure for clearance.

Thanks Mike.
I am pretty confident +55 on the front will be OK. No more for sure, but the wheels sit a little inside the fenders, and if there's rubbing it will be on the extremes of tire-turn, not regular driving/racing.

Thanks again for finding the cup2s for me (twice now), and shipping so fast! Looking forward to using the OZs on track.

The hoosier R7 is a very different beast of a tire than the old R6. R6 would drop off noticeably after just a couple heat cycles, and end up being equivalent to street tires (non r-comp) after about 10. I still ran them until they corded, about 3 DE days on a track like TWS. The R7 grips pretty good until they cord, which is still about the same about of time. If you run hoosiers, and want a full run of a DE, you either have to have two sets of wheels, or always start with a new set. For years I thought this was just how things were - until COTA. COTA is so easy on tires that I think you could get a minimum of two weekends from a set of R7s. I've yet to do this because I've never had the chance to run multiple COTA events back to back.

I like the Trailex a lot. It's very well built and has some nice features - open floor, storage, tire rack, fuel rack, road-rash protector, and a winch. Easy to tow with my SUV. If I had to fault it, I would say it's the deck height vs. the featherlight. It's about 5" higher, and the ramps are much longer - so it's a bit of a nail biter to get a car on the trailer and lined up - my RS had only 1" on either side of clearnance, so I usually winched it on.

I mounted the wheels yesterday, bad night pic below. Surprisingly, they weigh the same as the OEM set both with TPMS sensors installed and Cup2s. To the track to test them out this weekend.
46.1 lbs front
54.3 lbs rear

electronmike,
Damon,
The multiple times that I have contacted Tire Rack I was told that the Porsche spec Cup2's rears are out of stock, How was Tirerack able to find them for you, or are they the Ferrari/or/Mercedes spec cup2's?
