Just drill them out, you can buy a drill piston set for under $10 and takes less than 5 minutes.

What AE pistons do you guys use ? I tried the stock ones that come with the b5m (1.5mm,1.6mm and 1.7mm) and I do remark that they are not the same diameter as the xrays.
The xray's are 12.00mm spot on whereas the AE's are 11.80mm.
When I tried them two problem arose:
- The thickness wasn't the same I had to sand off the AE's to fit.
- And secondly I have found that the AE pistons had an awful lot of radial play hence why I measured them.
0.2mm on diameter is substantial, that's 3.73mm² difference ! A 1.6x2 hole piston give 4.02mm² in perspective !

Which you obviously found out for yourself as well

Thanks I can't remember where I read or heard this but at some point I was told so.
I think it could be one of my mates at the club who told me this which could explain why his xb2 didn't behave so well and he was a bit upset the last evening meeting.
The car was a bit all over the place and wouldn't hook to the carpet even with brand new mini pins.

Bent,
Looking to try out these tires. We run carpet at out track here in the States, but it doesn't have nearly the traction compared to the surfaces you run on.

As these aren't low profile (higher sidewall), do you run these without inserts also?
Schumacher claims that typically you don't, curios as to what others have discovered.

Ok is it right for these shocks to have alot of droop?
I built it per kit, and 30.5 stroke rear, and 24 front.
Also to go along with my question; does it seem right that I would have to run such a stiff spring to make it not donky kick?

I'm running 18 ride height with, stock front spring and yellow associated rear spring.

The geometry of the XB2 allows the use of quite a bit of droop when shocks are run without limiters inside.
If you want less droop just add limiters inside the shocks

Outdoors we always run the 1 dot rear spring as well even with as much as 120 g of weight added. Same piston and 400-450 cst oil.
