Ive been speaking to Tom Seal from D R Engineering about his Gripper limited slip differentials for the Williamsclio gearbox.
His site can be found here - http://www.racecar.co.uk/gripper/
To install the Gripper diff, Tom will need our gearbox, whether it be new, reconditioned or original. He charges £150 for a full strip down, clean and inspection. Parts needed are added on top of this cost.
To fit the diff, the crown wheel needs modification, but this is included in the purchase price of the Gripper.
Ratios and be custom made – but I will be staying with original.
The Gripper assembly is £860.
But to ensure the gearbox is 100% perfect – the extra £150 (above) has to be added.
If we can get 5 people to confirm we can get the Gripper assembly for £720 – but I might be able to improve his figure with a little persuasion.
My gearbox has started to whine ever so slightly – and when it goes completely I am seriously considering this modification.
Is anyone interested in the deal ?
