The length really wont matter as it's a start and end point of a theoretical cone.

Find a collette that fits well and protrudes the desired amount from the rear and protrudes out the front too, which ruins the clutch so grind it down from the front, doesnt need to be too accurate as it sits just inside the flywheel

grind it down from the front......from the front does nothing.... The problem is the amount of cone htat was sticking out of the rear.

With a NR flash it comes with 2 cones the 5.5 cone i used and did the following

Here is the difference a 5.5 cone has the same Dia as a 7 at the rear, and the same at the front the problem is always at the rear in this case.

I took the 5.5 cone down to 5.0, works fine its just a PITA to do.

Thanks for the info, tips and help.

I used the following Fly wheels and got the following gap between motor and flywheel on a stock 5.5 cone

Mugen 1.17
Arrow max 1.20

Prior to sanding thats the best I could get.

With the cone at 5.0 I can shim the clutch anyway I like

Here is some pics, The pics are messy but I am working away at things so, I like it busy

What he means is that some cones, while long, are smaller in diameter so the flywheel will go on them further.

I can understand that.

The 7mm cone almost sticks out the other side of the fly wheel and thats before you tighten it all down.

I would be worried that with that cone when you do tighten everything down it could create a problem....maybe

depending on the track, from what i found at the preworlds 18mm was perfect, were we run in our home track i go 22m, traction at home track is med and alot of sharp turns so i like alot of steering...

Yeah, the pic I saw of Robert's car and it looked like he mounted it the standard position.

I mounted a body like that and it is about 26mm from the bumper.

Also, I noticed if you mount it any less then the stock position (say 22mm), the front of the body sticks up a bit too much.

Anybody know if there are aftermarket fixed front axle shafts that screws on the wheels instead of the quick release type that fits the MRX5?
