cheers

Certainly do

Front:-
Shocks - Blue spring, No2 piston, 40w AE oil, middle on tower. outer on wishbone.
Camber link - 1A, no washers under inner ballstud.
30 degree caster, In-line axles, hub spacing up, 1 bumpsteer washer.

Rear:-
Shocks - Blue spring, No1 piston, 35w AE oil, inner on tower. outer on wishbone.
Camber link - 2C, no washers under inner ballstud.
3 degrees antisquat, long wheelebase.

Cells to the front and full minipins all round

If there's too much steering for you drop to a silver rear spring.

Is this a set up for other tracks too rich? or do you have others for say batley york etc?

how do the blue rear springs effect the car? ill be club racing at formby high, and it's 100% carpet, would the blue springs benefit me?

Thats pretty much how I always run the car indoors, although I normally start with a silver rear spring and the rear shocks in the middle on the tower. The blue spring is specifically for the super grippy carpet at Teeside it tends to give you understeer and grip-roll, the stiffer rear gets around both problems

Thanks for the set up . I tried it on Saturday and then again on Wednesday, ended up with silvers on the rear and was also running worn yellow mini spikes, left over from the outdoor season. Are the minipins much better, what do they offer, and how do they wear compared to the minispikes. I really don't fancy running new mini spikes in there once these ones have worn out!!

The car moves around less on pins, you'll have a bit less steering with pins all round too. Normally you get understeer on spikes and oversteer on pins, but Teeside seems to be the opposite for some reason.
You will defenately need the blue rear springs on pins, they will give you back the steering you lose going to pins and stop the rear suspention colapsing and making the car unstable.

I find the pins actually wear slower than spikes as you're not drifting about all the time.

You will have to be awake to drive the car on pins though, it should be well balanced but grip roll will be a problem on that evil green astro for the first couple of runs on the tires.
If you keep your head for the full 5 minutes though pins are worth half a second a lap easy

The carpet at Durham is grippy as well if I remember right! Do you have a good selection of pinions cos thte one for a 19 will be much larger than the one for a 12...
Mine is probably wrong, but I use a 23tooth pinion on std spur with my 12x2

[PaulRotheram]

use 23/24 pinion for a 19 turn.
