in the wet my cars rear is too stuck without removing any screws for flex,id like to loosen up the rear to get more steering as it understeers badly though the chicane
does ackerman affect low grip levels,as i have arm sweep i havn't got any shims,should i add some to get the wheels turning more parallel?

heres my set up

During practice yesterday I hit a car in the chicane that spun out. It was a very hard hit but the 1.6mm pin in my ECS shaft broke but I couldn't notice it. While going full throttle on the straight, the shaft popped out the barrel and the car was pulling to the left while I was overtaking someone and I was a half meter from the wall. The car pulled into the wall and the topdeck snapped in 2.

Rebuild it today and all other pieces seem fine including the bulkheads. I hope the chassis isn't damaged. At least there's no visible damage to it.

The car tends to want to keep rolling in the middle of a corner, less on power traction, more off power traction. Great forward bite. Car can wander a bit if the oil and springs are not right.
2.no layshaft screws no post:
-high rear flex. More on power steering than regular T4 set up, car rolls well. Good compromise between flex and steering. More steering than regular set up on high bite. More off power traction in low bite, but less on power traction.

With the lowered layshaft mount I feel like you can go up 50-100 both f/r to gain stability lost due to the increased flex.
would this work for blinky 17.5 ? or what would you change ?

Yes, the effect is very similar in 17.5. I typically run the same set-up in 17.5 and mod. I actually like to develop set-ups with slower motors because it is easier to identify problems when your car is going slower, and you are looking for corner speed to get fast laps.

It usually ends up translating well into modified, but I am not a crazy over powered mod driver. I like just the right amount of power as I feel I can push the car harder and be more consistent with it. Indoors, I hardly ever run anything faster than a 5.5. If I was running more power, I would probably change set-up a bit.

Bump for an answer.

I don't really like offset spurs. It seems like it either puts the pinion into the belt or into the motor mount (or closer than I'd like, anyway). The kit 84T/48P spur is non-offset, and the pinion goes in much nicer. But it looks like that's the only non-offset spur that Xray makes.
