whats the difference?
 

What is the difference between a xxx, xxx-cr and a bk2.
got a xxx and was getting another as a spare as its cheaper to get a doner car that buy parts!! would the bk2 be usable?
cheers for any help.

The BK2 has different gearbox, front and rear wishbones (you can put the front ones straight on but you would need the newer castor blocks), front and rear hubs, drive shafts.
The XXX & the XXXcr are more or less the same transmission but the XXXcr has had quite a few parts upgraded like - Diff halves, diff plates and hardware, front and rear wishbone, rear hubs, rear pivot block, front and rear shock towers, new steering assembly/rack, all of the components (wishbones, shock tower, chassis ,front bulkhead, kickup plate and rear t-plate are in a new material EA3).

Thanks

The CR and Bk-2 run different gearboxes. The Cr is a lower 2:43 gear ratio. The BK-2 runs a 2:61 ratio. The CR just runs the old XXX tranny.

The BK-2 is a sled............. stick with the XXX or CR...
