Changing the mileage on these is trivial assuming it's similar to the 32. You can make it show whatever you want.

While I appreciate the GKtech being a superior design, the amount you've had to fuss with it scares me away a bit seeing as this is a road car. Is there any reason I shouldn't just get some nismo arm mounts, and either whiteline adjustable bushes in the OEM/nismo arm, or JIC -10mm rubber bushed arms? That combined with ikeya or hardrace tension rods, and hardrace rear upper and traction rods sounds like it would be able to align my car at the theoretically ideal 350mm height without resorting to rose joints.

If the adjustable bushings from white line and the like tend to crack, what about shorter fucas with rubber bushes? The nismos are standard length, but it looks like once upon a time JIC sold shortened fucas with standard rubber bushings, and I could probably find a set. Edit: seems they might be too short though? Looks like they came in -10 or -20mm sizes.

They're discontinued. Is it worth buying a used set?

I guess whether I need adjustable camber in the front and more than normally available in the rear depends on how far I lower the coilovers, though it seems like adjustable castor would be useful at any height? My understanding was that reaching an ideal ride height would require a way to adjust camber in the front and more in the rear.

Just noticed this statement. Why the Nismo FUCAs with adjustable (white line/superpro?) bushes vs the regular arm? Isn't the Nismo arm for the GTST identical to the OEM one?

The arc bars I have aren't adjustable. They came with the semi rigid rear links and replacement bushings for the front oem links.

To clarify regarding sway bar links. I have ARC swaybars and ARC 'semi rigid' rear links that have bushes on one end and joints on the other. I've also seen Nagisa auto ones with joints on both ends (second picture). Not sure if it makes a huge difference but I thought semirigid would be better than full rigid for the road. Not sure what to get for the front links.

To be honest, it doesn't sound ideal from the perspective of a road car. I'm kind of surprised no one makes adjustable fronts with some sort of bush, either poly or rubber, instead of a beating. Unless there's one I don't know of. Might be better to just use adjustable bushes. Regarding sway bar links, are you using ones with ball joints on both ends, or bushings on one end and a ball joint on the other (semi-rigid)?

So how is the maintenance on the gktech uppers, are they better being Teflon coated or is it still a pain on a road car?

So the only arms you have with rose joints are the front uppers and front tension rods? Does anyone make front uppers with poly or rubber bushes (aside from Nismo which isn't adjustable and only comes in a single size?) And is the hardrace the only rear upper with bushes?

How are the ikeyas on the street? You are running the poly front tension rods / rear traction rods or the rose joint versions? And aren't the front uppers from ikeya fixed, so you have to order the right size? I think you have to order the rear upper in a negative or positive version also... GTSboy, what else are you running aside from the gktech front uppers? I haven't seen poly uppers for the front or rear, but the reason I was considering using the poly bush ikeyas for the front tension rods and rear traction rods was to reduce NVH as this is a street car. Not sure how much more civilized they are compared with the rose joint versions of the same product.

Well before I put them on since I'm going to need an alignment I was looking at adjustable arms, but I'd really prefer poly bushes to rose joints. I saw ikeya formula does adjustable front tension rods and rear traction rods with bushes, but it looks like they don't offer front and rear uppers with bushes to match. Any ideas?

We ended up chosing to have the shocks rebuilt with rubber uppers, and with softer springs (minus 2kg front and rear).

Potenza. I run the RE71R on my street car, it's fine. I guess they don't last as long as the RE004, but that's not as good a tyre as already stated above.
