That is correct. My shop tested both links. The older link gives about 3mm clearance with 11" OZ, no spacer needed.

The older tarett rear toe link. it's listed as "toe link all 981". Part# ERP981.009

Do not get the "newer" 981tlnk. it has less clearance than oem.

Nice. Still pretty cheap compared to cup2

Wait, what? So what's the point of the newer links? I thought they were specifically designed to clear a 19" wheel on the GT4 because the old ones wouldn't?

I don't see RE-71Rs listed in OEM sizes on Tire Rack's website -- did those numbers come from a rep? And are they actually available for purchase if we contact such a rep or do they just have pricing information before actual availability? If that's true though, that's a savings of almost $800 per set!

That's what I thought too.

from your first set of pics, looks like you have older "rod" end version. The better clearance version.

Yeah, Joe has the bump steer toe links, which are the third possible Tarett variant. There are the classic non-bump steer links, the new ones called "toe control arms", and the bump steer links that I believe are based off of the classic design.

Joe - don't forget another benefit. If you mess up an OEM wheel, it's about $1400 to replace. The OZ wheels are more like $450.

They had them listed but took'em off due to late fall availability. They are taking pre-orders now.

IAW with Bridgestone tech support tires are being made and stockpiled in Japan at present. Maybe they are expecting a run and are trying to avoid the ever present shortage Michelin is experiencing.

Well only if it's true that the old links offer better clearance, but that doesn't make sense to me. The new ones specifically say "Clears 19-inch wheel on a GT4", which leads me to believe that that's why they were created. Anyone feel like calling Ira?

I noticed no negative effect. However, I'm likely slower than you are, so who knows. From what I've read, no one has negative comments.

The Bridgestones don't last any longer, but they are 1/2 the cost. According to USC Trojan, they aren't slower either. Can't comment on that, my Cup II's are in a storage locker with 200 street miles on them. I saw the price difference early!
Was this for the 8.5" and 10" width wheels? Also, is the consensus that the 19x10 wheel is good for track use with a stickier tire?

Guys running OZ wheels, can you check to see if you have caliper rubbing like highlighted recently in thread: https://rennlist.com/forums/gt4/9266...-on-gt4-7.html

It's not the end of the world...it just trashs up your calipers, which you can't see anyways. For someone who clear-bra'd his steering wheel, it would be an issue.
