I'm going with the 1.125" TROPHY front swaybar and 0.875" street/race rear swaybar (or the stock Zanardi bar).
What spring rates do you have? Swaybars are an integrated system of springs, tire size, compound, vehicle weight, distribution, etc...
I'll have to check for sure, I've got the Tein Mono flex I think its 8kg on the front & 10 on the rear from memory
Haven't got the tyres yet but will most likely be the Advan A048 or the A050 235 front & 265 rear. probably the A048 to begin with.
I've got the Street/track bars front and rear.
2.5D neg front & rear
Front Toe 4mm out total. Rear Toe 4mm in total Rear.
Weight 1160 kgs. approx 400HP
If the springs are the same length front and rear, I would put the 10Kg up front and the 8Kg in the rear, and maybe set your front toe to 0 or 2mm toe out total.
I would also consider the larger front bar - especially if you don't swap the spring rates.
Ok, Thanks for the tips. I'll make the changes. I will order the front bar.
Also have you messed around with changing track widths? I've got a 15mm spacer on the front to clear the brembos, should i add the same size to the rear to keep things the same?
You could. Widening the front track should make more front grip, slightly heavier steering, and lower your front wheel rate slightly. More reasons for stiffer front bar and swapped springs. Its all a balancing act and every change affects the system.
Yes, I agree. I raced a different type of car previously, just trying to hit the ground running with a known setup.
Thanks again.
