If you lower you do not need the anti-dive kit. The anti-dive kits were desinged for rally cars who had to have good suspension clearnace for forrests etc. For a road car just lower it.

My old 2.8 handled like a dream with 1" lower (makes it -2" over a Laser)fronts , 145lbs springs and polly bushed TCAs and ARB. Standard rear single leafs. No dive, no roll and 100% fun.
