Oh cool, I didn't know that. Thanks. I'm gna call there tomorrow.

Using a set of curved body scissors leaves a perfect edge, takes 4-5 seconds pr wheel and only require 1 operation to get them done.
We never run foams in Stagger type tires since they perform way better with no foams both on carpet and astro.
For other normal 2WD front tires we never remove the center rib as this stabilizes the tire and keep the foam in place and keep the tire more consistent.
On high grip surfaces we even glue the foam to the wheel for even better support and response

Do you recommend gluing the tire to the rim in any way? These tires on a narrow Schumacher rim fit so tight, some at our track don't glue them at all. The sidewall is kind of a spring, and I've rarely seen them slip off while racing. Curious as to your experience.

Don't do like I did. Glue them. In a race they'll come off. A hard crash will undo them easily and trust me a little dab of glue will avoid you a DNF.
Even for practice I don't bother. I glue them. You don't need to be as thorough as the rear though. A few points is enough.

I did that for a few months... Never bothered to glue them as they were very tight on the rim. That was until I went to a race with them...

I had the same problem with 180 turns and some of the guys at the track told me to remove all the limiters and it gave me more steering! I'm so confused.

In other news, I learned that an XB2 can traction roll. My first race the grip was so high that I was lifting the inside rear into every corner and working to keep the inside wheels on the ground the whole way through. It was definitely faster in, but mid-corner it was exactly the same as all the 22s and B5Ms. I expected my purpose-built low cg rig to be more impressive in that regard. Second race, the grip was way lower and the car just didn't seem to generate any grip. Moving shocks and increasing droop helped but it was never really there. Hopefully the stability will come with track time and a little tuning.

Put them in a closed jar with 1/2 inch of acetone at the bottom and leave them for 48 hours. You'll remove the tires effortless and the wheel will be as good a new ready for a new set of tire.
It is spectacular when they come off in the middle of the race lol sometime you can finish the few last laps with them hanging on for dear life !

Could you enlighten me on the shock limiters especially on the front shocks? I always had the impression that limiting the shock extension in turn limits the weight transfer to the rear and therefore giving you more steering.

JConcepts also has narrow front wheels in the B5 offset.

Instead of measuring the wheels I actually mounted the XRAY wheels on the car with no tires and measured it front and rear and then did the same with the JC wheels (No tires) I run on my AE car....
Xray wheels
Front width: 242 MM
Rear Width: 245 MM
JC Wheels
Front width: 245 MM
Rear width: 241 MM
I ordered the -.75 hex's for front and +1.5's for the rear that should get my car to 243.5 Front and 244 rear. I did not see +2's at all, but maybe I didn't search good enough.

This is incorrect !
Removing shims inside front shocks will add droop to the front and thereby increase weight transfer to the rear on power = reduced on power steering out of corner.
Adding shims inside front shocks will reduce droop to the front and thereby decrease weight transfer to the rear on power = increased on power steering out of corner.
Removing shims inside rear shocks will add droop to the rear and thereby increase weight transfer to the front when braking = increase off power steering into corner.
Adding shims inside rear shocks will reduce droop to the rear and thereby decrease weight transfer to the front when braking = reduced off power steering coming into corner.
0 degree caster inserts will give more steering off power, not on power.
Using option 0 or 1 carbon steering extenders will improve mid and on power steering (ball stud closer to wheel).
Going to 5000cst instead of 3000cst wil also add on power steering.
