I instaled z33 sak yesterday and I'm getting extremelly bad ackerman and my caliper hits the coilover. They are BC BR series, so no external reservoirs. Was wondering if you have any suggestions? PS only getting 55 degrees of angle with inner wheel.
1. make sure your toe alignment is zero unless you want quick initiation and then its a few mm toe out. 2. Make sure your caster alignment is correct (less is better in this situation). 3. Increase the track width of the FLCA 4. Weld metal to the arm at the bump stop point if you have ground too much from the OEM aluminum. If it takes 2 less degrees of steering angle to keep it from binding then 2 degrees less useable angle is way better than 2 degrees more unusable angle.
or run less caster and wheel spacers or lower offset rims will kill understeer as well. honestly zero toe or .05 toe in is perfection reason for this is once load is transfered to the rear the thrust angle changes the toe causing it to toe out naturally. even toe will give better feed back and feal and allow for much easier mid drift corrections. as far as camber think last i remember kado is running like 5 degrees camber up front but just like above once the thrust angle is used the camber will change so under load 5 will become like 4.5 or 4 depending on your spring rate and of course what motor and dampening blah blah blah. so keep this stuff in mind.
you need to space out the front man. parts shot max makes rad wheel spacers. this will kill all your under steer whoes. and here is a photo of kado's car with the same situation so you know your not the only one.
In the picture I'm running different than normal. In the front I usually use an 18x10 +12 offset and a 18x12 +20 in the rear. 255 35 18 front 265-275 35 18 rear 43 psi. Adjusted track width to .25" on each side running 5 degrees of camber. I forget the rest...oh yah -10 caster.
