For you technical guys, I'll copy a reply that Ron answered on this clip:


"My highest level front suspensions are called "Track-Star GT" & require the engine to be moved back substantially, so the pulleys are behind the front axle centerline.

Craig's front suspension is my "Track-Star TA" front suspension. It is the meanest front suspension I know how to build ... without moving the engine back behind the front axle centerline. The LCAs are a special Laser cut design I did. The UCAs are on roller bearings. The shocks adjusters allow the ride height to change up to 2" without affecting the shaft gap showing on the shocks. It utilizes a special bump stop system for easy landings & consistent corner entry grip & braking.

The spindles are my GT "Zero Scrub" with my GT narrow XHD hubs. Bearings have twice the rating of street car stuff. The steering arms are slugged, so Craig can make them anywhere from 4-1/4" long to 5-1/4" long. Excellent for switching from autocross to road courses, like a lot of my Optima clients do.

Of course it has crazy high end hardware, Tubular Chromoly bolts with AN washers & Nylock half nuts on all the double shear mounts. 170,000 PSI 12-Point bolts & full height Nylocks for all the single shear mounts. Howe zero stiction XHD ball joints (not the standard versions). All chromoly rod ends, curved tie rods to allow the spindle to go deep into the wheels, which are 18x13 w/10" BS.

Craig's TA package has all of the possible upgrades over the "standard TA package. His came with a full range (70+) of suspension slugs, Caster Slugs & Camber Shims so the geometry can be changed or optimized for any set-up or any ride height he dreams up down the road. Plus Craig's has the triple adj JRI shocks with my special Race-Star valving & the Draco 9000 Series springs. Ridetech Triples with Track-Star valving & Draco springs are standard with the TA. Front Brakes will be my new StopTech ST60 Trophy system with lightweight (16.2#) 14" x 1.25" rotors.

The "Track-Star TA2" front frame & suspension is a lower cost version of the TA. It has the same frame, geometry & control arms, but uses lower cost shocks (Ridetech SA w/Track-Star Valving), Hypercoil 4000 Series springs, no C/O adjusters, TA2 Spindles & hubs with a 5/8" more scrub. It only comes with one set of slugs & Shims to optimize the suspension for the target ride height & setup. Everything else is the same.

The "Track-Star TT" (TT = Track Toy) is the lowest cost version. It uses the same frame clip design as the TA & TA2. But it uses off the shelf stock car control arms (non bearing), GN spindles, GN hubs, non-slugged steering arm, etc. It uses plain ol' grade 8 hardware. But it still uses the bad ass Sweet dual power rack & Ridetech SA shocks w/Track-Star Valving. It is designed for a guy that whats to have a durable, fun, safe, good handling track car (or street & track car) but isn't trying to set lap records. The geometry is "good." It is as good as I can achieve with all the shelf LCAs & GN Spindles. So it will be very good, but not in the same league as the TA & GT stuff.

Craig is pairing this with my "Track-Star GT" rear suspension which will make for one mean MoFo."
