Virgin builder

[Bonzo]

A warm welcome to the forum .... Great to see another West Country builder enter the affray

If you are planning an out and out track car & want to be competetive, personally I would be looking at high power lightweight engines

If the XR4 is a 4 wheel drive one the front hubs will not be suitable for the roadster .... Not such a big deal as standard front hubs are reasonably easy to get hold of.
