A few weeks back I attended an RMA trackday with Bookatrack to drive one of their Caterhams. I guess this is the start of a bit of insight into some of the other car related activities I get up to. Between 4 of us we hired a caterham to thrash around for the day. One thing that sets RMA apart is their trackday rules are a bit different, you can overtake on either side whenever safe (apparently these definitions are pretty flexible if you're a racer) and coupled with this people bring pretty serious cars. You can be hard on the brakes and turning in and a radical will ping down the inside and be gone before you can say "downforce". Our car for the day was a Caterham Superlight R300 on track tyres, these things are actually pretty quick and the impression of speed you get from hammering round just off the ground is pretty awesome. So you think you are putting down a fast lap and suddenly you will get overtaken on the outside by a full on race spec gt3 car..EPIC!
Our car was an SV chassis (the big one) due to having a few giants in our group and for some reason the pedals were set up to make heel and toe absolutely impossible, this really was a pain and took some joy out of driving the car because changing down under hard breaking is pretty brutal on the car and led to a few rear lockups.
