Our friends at Annex Suspension supplied us with their forged 4130 spindle. Previously, you would have to get an aftermarket part to be welded onto your new strut housing. Unfortunatly these are weak and tend to bend. The other alternative was to find some rare OEM strut tubes with spindels in excellent shape to cut apart and use; however, these are getting very diffcult to find. The Annex part is forged for strength, the right alloy, and is heat-treated to be even stronger than OEM. MCS also welded a gusset between the spindle and the strut tube to reduce flex and potential caliper piston knockback issues.
The high and low speed compression adjusters are found on the remote reservoir. High speed affects bump response, like curb hits, and low speed controls chassis movement, like roll and pitch. In our experiance we have found that having independent compression damping adjustment is a huge advantage in dialing in your suspension to a high degree, and we feel that it well worth the expense to have this capability. If 3-way adjustment is a bit rich for your budget or by rules, not allowed in your series, MCS can build you a shock to fit your class or whatever you are willing to spend. They can build non-remote reservoir 1 and 2-way adjustable shocks, two-way remote reservoir shocks, 3-way adjustable, and 4-way adjustable remote reservoir shocks. What is cool is that the remote reservoir shocks can be upgraded from 2 to 4-way very easily in the future.
The rebound adjustment is found on top of the shock shaft and controls primarily low speed rebount, although it affects rebound throughout the speed range.
We are going to be using Annex camber plates. We feel that these are the best camber plates on the market for the AE86, and they are adjustable in both camber and caster. This way we will be able to dial in the alignment settings we want while keeping the wheel centered in the wheel well. The Annex plates are CNC-machined from billet, have high-quality hardware and bearings, and are hard anodized for corrosion resistance.
