carisma gtb damping.
 

My gtb is massively over damped. Setting the f/r ride height is impossible.

What pistons and oil are the top drivers using on carpet?

Hi mate i'm running the pro pistons in mine, they are about £2 from Trackside Spares if you want to fit them, its very easy. It gives the fluid A LOT more movement inside the shock.

I currently run 45 rear and 37.5 front with the harder Black springs up front. Anything under about 40 on the rear with the pro pistons is a little soft for my liking. Tbh the pro pistons are a massive help.

Do you know the diameter and number of holes in the pro pistons?

I don't know the size of them but they have 3 holes in and the same diameter as the kit ones. They have the same number as the kit ones but the holes are bigger. You get 2 sizes in each pack.

Which size do you use front and rear?

I'm not sure, i bought the Green pro shocks with the pro pistons already fitted.

Buy the pro pistons, they are like £2 and will give you all the options of using thicker/thinner oils :)

Thanks for the replies :)

Pro pistons are 1.3 mm
shock oil allways run front heavy than the rear
my setup is
32.5 rear
35 front
anti role bar
1.2 front
1.1 rear
as a rule
softer you go more grip you get on the rear

As said just get the pro Pistons, they are a different profile and thickness to the kit ones, it's not just about the hole sizes.

Front: number 2 piston, 37.5wt oil, hard spring, 1.2 anti roll bar
Rear: number 2 piston, 32.5wt oil, medium (kit) spring, 1.1mm roll bar

Should be a pretty good place to start :)

I run 40 weight in the rear on mine now, ive tried 30 and 32 but find them way too soft, the back end seems to catch more on the ground :/ always seems a bit more twitchy?

I run 37.5 up front with the hard springs and its perfect.

The pro pistons are a must though, the kit ones are far too slow.

Just drill the stock ones out to 1.3 or even 1.4.this give you a quicker recovery off the jumps .you dont want to go heavy oil on the rear.unless you on a track with high grip and not many jumps.heavy oil will make your car double bounce on the jump landing making the car out control.
