From the thread:

"Hi Peter. I do not adjust the tension of the belts based off of efficiency. Obviously i would never run the belt Super loose or Super tight but i will run the belts on the loose med or tight side of things for handling purposes.
I assume that with the ever changing speed and load of the drive train their is no perfect setting for efficiency across the board so i generally tune the belt tension for handling purposes only. I normally run the front belt on the tight side and the rear belt on the loose side. I feel like with the rear belt being so much shorter it can have the tendency to apply a more abrupt load to the rear tires than the front. making the front belt tight and rear belt loose seems to help with this. I also think that the car might turn in harder with the front belt tight and rear loose.

Thanks "

A lot of the UK team drivers use them, but I couldn't get on with them (on carpet) so changed back.
They made my car a bit loose at the rear

Anything I could change from basic asphalt setup to help with a loose rear end?

On power


The front pushes also coming into turns also. I think that's started when I put the -.75 roll center on up front ...

Sounds like the problem I am having.

Try the front holes on the steering knuckles, make sure you turn your epa down too.

Then try 450cst oil in the shocks.

To gain turn-in but reduce exit steering:

- Lay the rear shocks down a hole (or two)
- Thinner rear diff oil
- Stiffer front springs

To gain rear traction:
- Remove some topdeck screws (I remove the inner ones from the main bulkheads)
- Move the rear wing backwards
- Add rear toe-in
