I didn't check before getting the club hammer out, so don't know what the clearance was like to start with :oops:

Heater unit needed a wiggle to remove after though!

One thing the bear in mind is how the cross member drop might affect bump steer and roll centre with different TCA and track rod angles, you could mitigate any changes if you could find some 3 door Cosworth front hubs but they are hard to get hold of and attract Cosworth tax...

Because the rack moves down with the cross member there will be no effective change to steering geometry as it will be no different to riding lower due to a full tank and 5 passengers.
Never been on a dyno but fully loaded on road tyres it did high 12's at Northweald.
The car was featured in Street Machine in OCT 2017 if you have a copy.

Will look out for a copy of street machine.

I imagine grip on the start line is a bit of an issue with a twin turbo 5 litre!

Yes, Northweald is not the best surface to launch from.

Yesterday I sorted out the gearbox support. I used a sierra

4x4 steel mount and spaced it down from the standard floor floor slots with aluminium blocks. I made new inserts with longer bolts to slot into the rearmost factory floor slots. As the gearbox mounting surface is at an angle I bolted a tapered ali block to it to get things level and inserted a standard 4x4 mount rubber into that. The plan is to probably get a poly mount which will be more compact and neater. The 4x4 cradle needed a bit of grinding out in places and local restrengthening to clear the gearbox casing but only because I needed it to be as far forward as possible to minimise re-positioning work on the exhaust. In hind sight shifting the exhaust boxes rearwards would have been easier.
