You'd be better to sell the corsa than take it out on the track,people are snapping up corsa's cos of their fuel economy these days.
Be careful fitting the air ride suspension,the chassis needs some serious modification,and if you don't do it right you can wave yer chances of getting it NCT/MOT'd goodbye!When I was finishing up the 300 I fitted an air-ride from a citroen dx,brought it to the NCT/MOT centre and they didn't even want to look at the thing,it wasn't intended for road use much if at all,but it's a pain in the arse bringin' it on the back of a trailer to race it,I'd rather just drive it there!
When I'm finished the 300 and I crack open the corsa me first order of business is stickin a windows pc in there,and installing a qwerty keyboard and trackball on the steering wheel.
But I won't let the insurance company know about it
