Pete has put up the spec of his 306 on northloop,

My car is standard engine (soon to change hopefully!) with decat, magnex and an induction kit (for all the good it does?!), and a sore rev limiter. Currently running on kw variant 2 coilovers, with thicker arb and torsion bars at the back. Also soon to change to some GAZ double adjustables, as soon as I get them back (hopefully some rose jointed adj top mounts too)! Stripped out, SD cage, weighs in at approx 1030kg without driver. Has some AP brakes 295x28mm with 4 pot calipers (these are awesome, first time I used them at Cadwell) and yoko a048's on Team Dynamics wheels with melted inserts.
