Suspension needs thicker torsion bars (27/28mm), 24mm rear sway bar, knuckle risers, and stiffer rear springs to handle better.
Understeer is there, but the main problem is the rear end squat which pulls the front off the ground- meaning you need to load the front suspension up before turn in.
I either ease off, or left foot brake while keeping the boot in,
and the locked diff brings the arse around for you.

Still learning though!

All of this planned, along with shortening to 4.3:1 diff ratio
as the car pulls around 80 in first, 120 in 2nd, and around 180 in third with the 4.11:1- taking too long to get up on cam (5,000rpm) especially out of hairpins like onto the straight @ Wakefield. Changing gears at 8 until shorter diff goes in, but it pulls there no problems- all the internal lightening means she just spins up, and if you dont grab another gear you'd end up @ nine in a flash.

Long run- probably just a newer ECU so I can squeeze the most out of it. Im reluctant to spend the money on taking displacement out- however, if the rings wear quicker than anticipated (forged pistons slap when cold until thermal expansion occurs), I will fit 3.0 pistons and liners, bringing comp down to around 10.8:1, but boring it out to 2.8- so I should get close to the 230-240@ wheels mark that way. Then its over for her and onto the next one! Cheers Jules
