Bought one from Harry hockley for around £1400 plus vat the best money I've ever spent on the car. Completely changed the car in a good way long first gear them sort 2ed 3erd and 4th car probleley only does 80 ish in 5th. The LSD from them has broken twice so I'm currently having them make one with a solid cross and less ramp angle.
Good people deal with and a lot cheaper than Mat.
