FSR, the Ava setup you see from JP3 on the AC board is just bought parts from them and not designed by Ava itself. ClimberRN and AC had a setup very similar to his and all 3 were failures due to severe bumpsteer.
The best setup out there is ClimberRN's(current) and is worth the 900 bucks. For those that haven't gone out and tried to do a real custom setup the go out and start pricing the parts yourself.
FYI the price for steer parts at Peak Nissan are
CL=179
Complete tie-rod assembley=129(set) X 2
total = 440 for a stock new setup.
Sure you can find parts cheaper BUT you still hit atleast 400 for a stock setup. My point is that if you want a strong setup it is will cost more, alot more.
IMO SLR's is WAY to much for what they offer. It isn't even a complete redesign. Also those tie-rod adjusters are going to snap, just give it time. I know I could break them.
I know of 2 guys that are using Ava parts and will be very similar to ClimberRN's setup and will be slightly cheaper and even stronger, and it isn't from any of the current companies.
Other points to consider: Once you have a super stong steer setup, you need to consider the next weak point. Balljoints(given) you will tear through these faster. Your steer box will probably go with a lot of abuse. And you will literally tear off the idler arm from the frame(possibly). You may even snap the spindle.
