XRAY - Model racing cars

This is one from Jilles that worked really well last year: . Might be a good starting point. If the tyres have a large diameter then have a look at this one: .

These should get you going. But I also suggest you visit the team XRay pit at the SnowBirds as the team will be happy to give you some advice on how to adjust your setup to the extreme grip conditions there.

Ya, I think I'll bug them! Good idea.

What are these silver and gold shock springs? Where do they stand in relation to all the other xray springs?

See the fourth item in the T2 FAQ thread:

OR you could just run a foam class with a mod

The oneway seems to be the hot ticket has anyone tried the diff up front ?

All the changes combined to give me the handling I needed:

- changed body from PF Stratus 3 to PF Mazda 6 to get more front bite
- increased rear ride-height by 0.2mm to get a bit more weight on the front wheels
- reduced camber all round by 0.5 degrees to get a bit more side bite (too difficult with the one-way)
- added 1mm shim under front top links to get more front camber change (more front bite mid corner)
- moved front shock one hole out (3 to 4) on the shock tower to get more steering in slow tight corners
- reduced front track width (smaller shims between pivot holders and bulkheads) to get more front bite
- increased front toe-out from 0.5 to 0.75 degrees to get more steering mid corner in tight corner
- reduced the Ackerman angle (4 to 2 on the servo saver) to give the car more neutral steering through the corner (with all the changes it would have been to aggressive on power otherwise)
- two extra screws in the rear bulkheads to remove some rear chassis flex

You may not need all these changes, but most of them contribute to getting more front bite.
