thanks all, so its basically just ignore the letters
Got a question about the risers on the EC
A lot of drivers are removing the gearbox risers and using either the std towers or the carpet towers but what advantages/disadvantages does this have when racing on carpet/tarmack using rubber tyres? I had a bit of success with the ec as it was bult out of the box but carrying out these modifications in the hopes of getting the car to go faster has left me chasing setups that work. Can someone explain this issue to me please?
Thanks
Paul

To me, when I took out the risers and raised the front inner camber link location 2mm above stock and used the top hole on the rear tower (rubber towers) it made the car flow through the corners much faster but it still felt very stable and calm. It didn't get twitchy at all.
Can you recommend a good base setup for rubber tyre tarmac and carpet then please Jon. I need to work out if its me or the car and at this point i'm beginning to think its me!

As far as I can tell the only real difference between the carpet and rubber towers (other than more holes in the carpet versions) is the position of the camber link holes.

Mutley- For asphalt, I'd start with the kit setup, just remove the risers from under the bulkheads and between the motor/layshaft mounts and top deck. Then move the rear camber link to the top hole. Drill or slot the front camber link in the tower 2mm up to make up for the tower being 2mm lower from removing the risers. This is a good starting point. For rubber tires on carpet, try Weylin's setup from Vegas. There's a few little detail things he did on that car. Follow his setup sheet and that should be a good place to start.
Skiddins- I know a lot of guys have run the carpet towers with the risers removed. It will raise the camber link like you need, but it also moves it out a little bit. I haven't tried this myself but it is something that should work too.

I have the rear inner link as high as it will go without modifying things. I normally ran the rear link in the low position when I had the risers in. So lowering the bulkhead and raising the inner camber link should keep the link at the same angle. When you raise the inner link, that lowers the roll center on that end which gives that end more grip.
Thanks Jon, at least ill find out if there's something up with the car that I haven't spotted or if it's me now. Next club meet is on Thursday - I'll let you know how I get on!

Also what does moving the camber link out on the rear hub do? raise or lower the roll centre? i have mine on the inner. and what are the effects of this?
Thanks guys, i am only now starting to vaguely understand set-up and want to know what effects lowering and raising the roll centre are. and how i can use them on certain track conditions.

Basically, a lower roll center will allow that end of the car to roll more. Usually more roll = more grip (to an extent.) And usually a higher roll center will allow that end to roll less, keeping it flatter and yielding less grip. Try and keep the amount of roll balanced front to rear. You don't want the rear to stay too flat and have the front end dumping over or vice versa.
