Can i change out the cup suspension linkages with ERP stuff ? This would eliminate some of the rubber and make alignments easier. the rulebook says you can change the links just not the length correct ?

I dont see anywhere in the rules that says you can change them except for the length. It is my understanding that you cant change anything except now clutch and control arms. maybe I missed something.

You can NOT change any of the arms to ball links.....GTC must be factory delivered.

Chris :

GTC3 - 996 Cup Cars

A. Tires are free.


C. Updating and backdating within model type is allowed.

D. Body parts may be replaced with stock factory parts.


E. . In GTC3 and GTC4, wheels must be 3-piece wheels of the same width, diameter, and offsets.


F. GTC2 and GTC3 cars are allowed to replace the pressure-cast aluminum control arms with steel

control arms of identical dimensions.


G. GTC3 cars may replace the Cup clutch with the GT3 RS or metallic GT3 RSR clutch.

H. GTC3 and GTC4 may relocate the battery to the passenger footwell in a sealed container.

Relocated batteries must be sealed dry cell.

So who makes the steel arms that are allowed to be changed ? PMNA ?

Rick DeMan

Those are Fabcar arms, available thru Smart Products. No need for these arms. Expensive and the factory ones have no issues.

AndyT

OK great. Spending is out of control lately and my other car still needs some work : (

Are you fixing that gearbox issue, I know someone (two posts above) that does a good job.

AndyT

yup I spoke to rick at the track but became too involved with the cup car to deal with it. so probably over the winter I'll do the gearbox : (

Jerseybean

Anyone check over the cup car for you yet? These cars often have very abusive lifes and sometimes things are not what they should be. I'm still fixing issues with the car that was left over from It's Rolex days.

Haven't the ball joints in the front control arms been know to fail? Not a "defect" per se, but something to think about for maintenance? Agree the Fabcar units are cost prohibitive.

AndyT

they are asking 1300 a piece for those Fabcar parts. ERP makes some stainless steel "pucks" i guess you would call them that replaces the rubber in the control arms. Is that GTC legal ? I can't imagine they would let us run the Fabcar arms and then put in the crappy rubber pucks

It is my understanding that if the rules dont say you can do it you cant

Rick DeMan

The metal pucks you refer to are copies of the original GT3R parts. They would NOT be GTC3 legal.

The ball joint problem is only from improper over-tightening of the joint itself. they stretch and then fail. If properly installed they will last a long time and be totally safe.
