I removed the front hubs off the convertible to place the group 4 hub/disc assemblies and ensure everything looked OK.
Well, here's a couple of pictures of the difference between standard TR7 brakes and the rally group 4 ones - massive isn't an understatement!
I also found some rather disturbing things whilst I was about all this though - see the pic of the nearside strut etc of the convertible.
1. Get the group 4 brakes machined so that they can be fitted to BRP.
2. Plumb them in and make sure all is well.
3. Replace the struts on the convertible with a pair of built up refurbished struts I have (thanks Martin Knapp).
4. Fit the vented discs and 4 pot calipers that come off BRP to the convertible.
5. Plumb them in and make sure they work in time for it's MOT in May and a holiday I am planning in the Alps for my 50th birthday.
