A coulpe of questions , any feedback would be great.

1. 25/640 18 fitment on 05-09 cars any tips on adjustments required.

2. Do Cup"S" front trailing arms fit on 2006 Cupcar.

3.Do Cup "S" /2011 Cup exhaust cams fit in 2005 cup engine.

4. Arp conrod bolts Part No. to suit 05 on cup. (ARP have no idea.)

 

1. Wider wheels (prob half in minimum) and work with the setup/alignment on the front to make sure of clearance.

2. Assuming you are talking about the diagonals to adjust anti dive/anti squat. Yes they bolt right on. If adjusted right makes a nice difference in braking power and rear traction on power down. Can be used with the adjustable upper rear links to adjust the wheel base. Unless you really have a good engineer you can cause more harm than good.

3. Have to check to make sure, but yes I believe so. (might need a different cam tower) The cams probably wont help unless you have the later dual resonance intake. That is the restriction on the earlier cars.

 

I had no problem running the Hoosier 25/650 fronts on my stock '08 cup. They were fabulous. Wish the 305 rears would have fit.

 

The exhaust cams are to go with a the Cup"R" intake , 3.9 kit and RSR headers.

The Std 24/64 have worn through the in guards just behind the side markers,
Some cars are running the 25/64 on the std rims so I was wondering how they
achive clearance.

 

So the 25/650 hoosiers clear with out changing the wheel placement or moving the inner guard .

 

You might need to reduce the caster with less shims in the control arms or rotating the pucks in the arms. If you go with the Cup S diagonals then its very easy, just lengthen them. You still want at least 7.5 degrees of caster though. with even numbers right/left.

 

I guess it's car dependent but they fit on my '08 with no mods.

 

Thanks for the feed back . Have ordered the Cup S trailing arms.

 

Has anyone run the larger 2011 cup R intake manifolds on the earlier engines.
