Default Have you spent the extra cash for poly bushings?

As I'm seting up my track/TT car to this point I've not skimped on anything. With the suspension I'm installing Pfadt shocks, comp sways and Hyperco T-1 springs. In addition I will be running A6/R6's

The Question is this..... with the car only having 3K miles on it would you pull the trigger and buy a Control Arm Kit with Poly/Aluminum Sleeves and Camber kit? Use the OE bushings with the camber kit or skip the camber kit till it's time to replace the bushings and do it all then? It's almost 900 bucks I could put some other place or would this be a good investment now.
Thanks for your input

Installing Pfadt's poly bushings in my car was the best performance mod I've ever done by far. That along with Gary's shock bushings dropped my lap times at Rd. Atl and at CMP by 2 full seconds.

If the car is track only and you are after the last competitive edge - go for it ! If the car is a combination street / track car like mine is, I would wait. The stock bushings will serve you well for quite some time. The poly bushings will be a PITA to live with on the street requiring frequent disassembly and lubrication to stay quiet.

Bare minimum get the camber kit installed. Without it, you're going to get tire 'roll over', and excessive wear on the outside edges will trash your tires prematurely.

Good luck,

I'vev been running the Pfadt poly bushings on my street/track C6Z for over a year now and have no squeaking.

I recently put in Gary's delrin shock bushings after my rears completely collapsed from track use.

I also highly recommend the camber kit as I can easily switch from trac to street alignment in between events by just removing some washers and resetting the toe.

Poly bushings were one of the best mods I have done to date...one of the cheapest too.

Poly's it is...... I know if I don't, I'll regret it later
Might as well do it when I'm setting the rest of the suspension up.

Thanks for the input guys

No need for a camber kit...

Forget the polys and get the spherical bearings...odds are, if you will be tracking the car competitively, you will get them later anyway...do it once, do it right!

Oddly, you can get away with less camber if you go to harder bushings, because they deflect less. I run PFadt polys on my car and they were a good mod. Turn in was immediately better, and tire temps (across the tire) got more stable. I don't find them particularly noisy, though it is a track car, so it makes all sorts of weird sounds that a street car doesn't.

If you go with poly, make sure they fit correctly when installed. Also make sure they are lubed correctly. And, I would add some provision for grease fittings, and make sure the grease can get into the center pivot point of the bushing correctly. Poly usually develops lots of stiction to metal over time (i.e. as the grease gets pushed away).

Polys are cheap if you don't value your time.

My Pfadt polys are quiet, 7 track days in, about 2k street miles. I cut the big ones in half when I installed them, fwiw. I plan to lube them 3x/year or more if needed.
