Put simply, when I lower the links, I get more grip.

The latest setup I ran 0.5mm on the inside rear with 4.5mm on the outside, this seemed slightly better still.
But the rear link is getting a bit too close to the wheel for my liking, might be able to get 5mm at the rear provided the wheels aren't too soft.

While the car is loaded (battery ect) sit it on a level surface and back out the droop screws. If the front comes up...you found your issue.
If your using droop blocks you need to be checking under the corner of the a arm...not under the knuckle/chub.


If this does not work pull the shocks and check for pin binding.

What do you mean by, you found your problem if front comes ? What would that problem be? Also you have a pic of where to check droop at the front? I have the same issue. Greatly appreciated.

If your spring collars are cranked down and you unscrew the droop screws while the car is sitting on the tires (and the front lifts up)..your droop screws are setting your ride height not your spring collars.
If your using Hudy droop blocks and getting a 6 reading under the c-hub tit (for lack of a better word) not the outer corner of the a-arm...I can just about guarantee you the droop screws are setting the ride height not the springs.
If it's set this way...you have zero droop (not good).
I don't have a picture sorry.
If this is hard to understand just set droop over ride height with a normal ride height gauge and there will be no issues.
Hope this helps.

Hey guys. Just picked up a T4 to race this summer. Planning to run the 17.5 blinky class. Im trying to figure out starting gearing but cant find a gearing chart anywhere. Last yer I ran the tc6 and that manual had a gearing/FDR chart in the back that I found really useful. Is there something like that available for this car?

If not can anyone help me get close to a 3.7 FDR. Thats about what my local track liked last year and where I want to start. BTW, I'm using 48 pitch gears.

Thanks for the help guys.

78/40 puts you dead on a 3.7 in 48p.

What part number do I need to run the optional, two piece lower suspension holder in the front of the T4?

I can't seem to find a 52mm ecs replacement bone for the 2mm pins. Does anyone know of a place that has them or the part number?

What would people do to prevent the rear breaking loose late in the corner, like deep into its roll. Lower roll centre on the rear? Softer rear roll bar? More rear droop etc
