Getting more legroom for Disco 1 driver?

Hmm, looks like we need to do some investigations into the seat runners then, as something is clearly not quite right if taller people are fine! Thanks for the info

P.S. Yes Party Monkey, Carl is really enjoying it I think and I get to drive it now and then too (as I've sold my RRC)!

Check the diaphragm under the seat base, if that's gone, then you will be sitting too low, it's a very common fault with the Disco 300. Getting a new diaphragm is impossible though, I fitted a set of seats out of the RR classic. The rear ones are a straight swap, but you'll need to make up a framework for the front ones. With the RRC seats in, you are a little higher, you can also adjust were you drill the holes for the runners.
