U caved in then Paul!!
You won't regret it as the car is awesome!
I ran mine at chadderton also qual 8th and finished 5th
I will post my set up I finished on hopefully tomorrow.
I haven't added any weight to my car, personally don't think it needs it, big changes were short wheel base at the rear (2mm spacer at the back) hub side still 2mm either side of the hubs. I also lengthened the rear link both inboard and outboard.. Moved rear shock to the second hole in from the outside and ran the front hubs low (1mm top and 0.5mm bottom)
