I must admit I would rashly perhaps assume any shocks which mount in the same way that have the operating range of 45-56mm should fit? Tamiya TRF's maybe for example?

Something I wondered, as my Mustang will be shelf bound mostly, is if you can fit brake discs to make it looks super pretty? haha! Sounds daft, but it just occured to me having seen the E10 which has them?

Cheers!
