If so, how much difference did it make for you ?

I had my TC out today with a complete new setup based primarily on Hara's with a few custom changes of my own based on my recent bedtime reading on setup theory. The initial setup worked quite well and got even better when I lowered the rear RC a bit.

Cheers

I am running the cut rear deck outside on parking lot tracks. It just seems to smooth out the car a bit. It's more consistent overall in lower grip conditions.

you can find it on hara's car from reedy '08

Thanks,

Yellow: 12.8 lb/in
Grey: 14.0 lb/in
Black: 15.1 lb/in
Purple: 16.2 lb/in
Red: 17.3 lb/in

Oh, the new black colored silver and gold springs are the same as the old ones. They started coloring them black a few months ago.

Hara and Korey use a 1.1mm shock piston diameter.

What's the deal here (volume change) ?

Thanks

They didn't seem to pack up as much. The 3 hole pistons had a softer feeling, but they packed up quicker. So they would feel soft, then feel stiffer if compressed quickly. The 2 hole pistons just felt the same all the way around.

I know Hiro has been doing some testing with the 2 hole pistons again, and he seems to like them. I run them when the grip is very high, because it seems to make the car more consistent. The 3 hole pistons tend to make the car very reactive initially, but they can make the car feel odd when the grip is very very high unless used in combination with very thick oil.

This is just what I have found though. Id say it's worth a try for yourself as well. It really depends on how much static grip the track has. That can influence the results drastically.

I've also use PRS spurs and they work fine...they are only made for 2 screws though - http://www.precisionracingsystems.com/browse
