GS FONZy

The rears on the GS are almost identical to TT calipers, so I would say no need to upgrade unless you are goin to be tracking the car.

Ok I will probably just leave the rear alone then. But as far as why I am upgrading the front brakes.....Why not? I already have the wheels and ss lines. It's just another modification to add to the list. I am not too worried about stop time, or auto crossing the car, to me it's all about just having a nice custom ride. The more tasteful mods I have done to the car, the nicer the car feels to me. It will also make the front brakes look less whimpy with my 19's on there. I guess it's just for the image, and bragging rights somewhat

Nice, I'm getting my calipers back from the powdercoater in 2 days, then I will rebuild with new seals. I will post some pictures when I get them back.

if you just go out and purchased the rebuilt ones, what about the bolts and shims?

lextechGS

iTrader: (2)

I would think you could use your existing bolts, they should be the same thread pitch. Shims and hardware kit you would have to buy, inless you bought aftermarket pads which sometimes come with the shims. I found an e-bay auction for OEM calipers that look like they are in great shape....the bid is currently at $99 with no bidders. Item number: 150404927610 on e-bay

I had warping problem with the ls400 rotor... you might pay attention to the air cooling system that already exist. I have an extra thick rotor too.

How much of the backing plate did you have to trim off in order for the caliper to fit? That's really the only part of the job I can see myself wasting a little time on.

PHML

iTrader: (33)

I didn't trim anything. I folded it twice with pliers....each time flattening it was much as possible. Just make sure nothing rubs against the rotor shield/backing plate.

oh ok thats cool, how wide was each fold? ( how much material was folded back each time?)

PHML

iTrader: (33)

Each fold was like the shape of a narrow slice of pizza (triangular) at about 1 inch at the widest.
