Yes the ceramic bearings are a very nice upgrade. I have trouble sometimes remembering I’m going Indy Car racing on a go-cart budget, so the standard ball bearings keep me within a reasonable budget.
The same applies to the new engine combination. I did set the car up for both SBC and BBC. However I’m changing engine strategies for a less expensive (slower) combo and run a boosted Toyota 3 liter 2JZGTE.
I haven’t set the tire, spindle, scrub yet as I need to sell my 8-71 blower to finance that part of the project. Nonetheless, I’m a running Ford spindle, straight up, without camber. So any scrub radius adjustments will have to come from hub, wheel and tire diameter adjustments. To your point of adding KPI, I did look into 10-degree sprint car spindles to help the scrub. However, from my dirt track oval racing experience I know extreme caster, camber and KPI have a chassis jacking effect. So I’m sticking with the “less” KPI Ford spindle.
Will shoot pics when I get going.
