Off the shelf with the sawdust oil they are OK in the low speed, but lack a real knee point and are basically linear. High speed is awful. With the Penske oil you get a little bit of a knee at 1-2ips but still the same crazy high speed, it's just lower force so most track stuff is totally fine. Tbh it's great at BRP and SoW.@refirendum
It was one of the first mods I did and don't remember. My focus at that time while the kswap was in process was to properly convert the rack by removing the piston. I didn't even focus on suspension geometry until later once I worked all the kswap wiring bugs out.
The Penske 3W is 13.7cst @40°C. I was figuring below 20cst would be good because the car weighs <1950 with <900 over the front axle.
Most shocks seem to be valved for 3000-3500lb cars.
