Cortina front uprights on an Indy
As I understand it, the Indy wishbone setup is designed for Sierra (modified by MK) front uprights, can the Cortina (Mk5) uprights be substituted with
no modifications or are different wishbones/balljoints required?
If the Cortina stuff can be used I presume MK knock the modification price (of the Sierra uprights) off the kit price?

No - Cortina uprights can't be used with Indy wishbones. The geometry is quite different between the Cortina and Sierra hubs. The MK mod to
the Sierra hubs is to re-drill the bottom ball joint tapered hole to suit the Maxi ball joint which MK have designed into the wishbone/car.
Is there a reason you would want to use Cortina uprights?
If you have a pair of Cortina uprights and you want to build an Indy, sell the uprights for the good money they are worth and use cheap as chips
Sierra hubs.

I read somewhere on here that the Cortina geometry was better than the Sierras, and thought this was on an Indy

They are substantially lighter than the Sierra ones, also more compact and nicer looking.

Guess I'm going to have to. And I'd planned to spend the weekend rebuilding them too, bummer.....
Thanks.

I don't know how the geometry compares, but the Indy is obviously designed for the Sierra uprights. The good thing is you probably won't
need to overhaul a pair of Sierra hubs other then tidying up the calipers.
As a bonus, the money (~£70-100) you'll get for the Cortina uprights would pay for a nice set of grooved discs to go on the Sierra hubs

or of course use the uprights you have and buy a locost chassis from mk (quite similar to the indy) ask them to make it suitable for a dedion rear
axle so you can use a sierra dif and rear end, I'm sure they'd be willing to sort something out for you!
