I installed the Perrins ALK on my STI and never looked back. It was by far the best mod I have done to the subaru including EM ( stock is stinkin fast to begin with ). If the evo already has killer handling I cant wait to see what it does with the alk installed.

This is all great feedback! The ZERO offsets versions will not happen right away, but the more people bugging us the better chance it happens sooner.
Regarding pics of them installed, we have some plain protos installed, and as soon as we get some parts back from anodizing, we will snap some pics. Here is a pic of them installed on a legacy GT. This is similar to how they are installed on the EVO.

You know, you're right
From Street Mod Rules:
"Suspension components are unrestricted as long as they use the
original attachment points. For the purposes of this rule,
“suspension” is defined as any item that is designed to move
when a wheel is deflected vertically. This includes shocks and
struts, control arms, steering knuckles, uprights, etc., but not tie
rods, steering racks, and subframes. In addition, shock absorber/
strut upper mounts are to be considered suspension components."

I think this product should be good to go for SM/SM2.
If Perrin made a version of this without extra metal in the bushing, it would be good to go for SP, as I interpret the rules:
From the Street Prepared Rules:
"Suspension bushings may be replaced with bushings of any materials
(except metal) as long as they fit in the original location.
Offset bushings may be used. In a replacement bushing the
amount of metal relative to the amount of non-metallic material
may not be increased."

DaveMAC,
For STU, they would not be legal. The "No metal for bushings" rule makes these bad. But good because they work good. We can make some in delrin, but the problem is how long they might stay tight. The teflon lined bearing stays nice and tight for a long time.

Forgot to put that! $229.99 is our price.
NVH is not noticable on cruising and normal driving stuff. When pushing hard, at higher speeds (like 80+) its a little lounder, but not as loud as soild strut tops.
The ONLY time they are harsh is on big pot holes. Its like the difference between 17s and 19's when running over a pot hole.
