Why does that run off 75% of the market? You guys don't want more adjustability? Doesn't matter. Porsche people are no as fickle as other owners, this just as well be a 911 v-8 transplant kit. Plus, street car guys are even more prone to keep things as factory tidy as possible so this leaves race group target. I can't see how this can be accepted for 944 Cup so regardless whether you could homologate this through PCA (basis of more than factory maximum caster), most of the 944s that race in PCA in the SP1,2 and 3 classes also double into 944 Cup which is VERY strict in line with as per factory allowances. Left it at work on the charger. Should be going back when it cools off this evening to pull some duty on a personal front. Try me back around 7-8pm.

Lane....just throwing this out there even though technically, the "point" would still be the same position but PCA rules specifically say that all suspension pickup/hinge points should be the same as stock and while this is open for interpretation as far as the placement of the FG a-arms, I think any competitive advantage (i.e. more caster allowance than anybody else) would outside the realm of the spirit of the rule. Heck....they just started allowing aftermarket a-arms that DO remain exactly the same. T I'm not sure about that T. I've had Fab Car after market a-arms since 2003 on the black car and, to your point, they mimic the stock ones and use the standard size caster block from Racers Edge. They did just change the rule to allow the adjustable top mounts for the struts. Andy, if you guys could make a cheaper stronger version of that you would have lots of takers. Racers Edge wants $600 a pair.

Here is the picture of what would be offered. Instead of putting the bearing in the castor block, ours is on the control arm. Also, ours is in double shear whereas the Racer's Edge piece is still in single shear. I have been sending these renderings out to try to get a ruling on them. They are without detail to protect our design. If you show anything to anyone, please use these. ![](http://fastguys.com/images/lcarender1.jpg) ![](http://fastguys.com/images/lcarender2.jpg)

Racers Edge wants $600 a pair. Notorious G, the 'Fabcar' arms are automatically homologous because they already ARE factory arms. Fabcar used to merely take the early steel arms and strengthen them by strategically boxing them with sheet metal. The later ones, without using a factory core are made of chromoly steel but still are modeled directly from a stock arm's dimensions. They conform in every way with the dimensions of the factory arms and use the factory eccentric for caster adjustment whether you have aftermarket caster blocks or not. Same thing with the Charley Arms. The fact that the adjustable camber plates were just made legal solidifies my point of an a-arm with potential competitive advantage not being legal. T

Andy....PM read and I'll check with a couple of posters on Rennlist that are closely associated with the rules committee but the way it generally works is - suggestions and proposals are put forth in a few week window once a year for consideration.
A vote takes place when that window is closed but there is no guarantee that a proposal will even get a vote for that period.
Look, why don't y'all consider increasing the thickness of the billet by bevel and welding say a 1/4" plate to each side in the area where the caster block goes....?

Guys, we really need to borrow a late geometry control arm (88 and up). We can pick it up and bring it back to you within a day or so. We just need to take some measurements. PLEASE, somebody help us out if you can.

Andy, I told you I have one.....if not where I said upstairs, you can pop one off my turbo in 2 minutes.
It's already up in the air and the bolts are hand tight.
You can feast your eye on the third variation of the aluminum arm, from a 968, same dimensions as all late ones but they added a tab to connect the 968 Club Sport brake duct that scoops air into the rotor.
AAMOF, if y'all were to add this, could be an additional selling point because people generally have to mod the early late ( ;D) ones when they want the factory air scoop.
Say the word and I'll let you know when I'll be there.

Progress is good.
I'll call Russ and get him to drop the arm off. Thanks again for the help.

Yup, that's the ticket.
That duct mount tops it off.
There aint' enough chassis clearance for that inboard grease fitting though.

It'd be better if I could meet him in BR sometime. Maybe lunch break for him....? Or, is it possible to bring by Paul or Carver's shop and I'll just swing by there and grab it...? I'm waiting on the frame shop on that smashed ti, or else I won't be going by the shop any particular time. T
