Jerrick - You are spot on when you say that going for a linear rate is what makes such a big improvement to confidence because of the more consistent characteristics in roll. This particularly applies to the rear where the rate goes from 3 kg/mm to 8 (horrible on cold tyres)!!
Just a few questions;
Could you confirm what your standard spring rates are?
Does the damping adjustment affect both bump and rebound?
What is the overall travel of the front dampers, excluding bump stops
In certain forms of motorsport (production class) we can use coil overs, but have to retain the o.e top mount - would this work, I know this is not ideal as the centre bush does not rotate?
Thanks
Yes, once you are use to linear rate springs... its kind of go back to Progressive because you are just feel that "little" bit unsure footed.
I had been developing another line of coilovers for the more Luxury end of the market (Audi, BMW, Lexus, Etc) and they really transform how the car drive...
Especially on the Lexus where they are very "comfort" focus on the factory setup to the point where it feels like all the weight of the car is on the front outside wheel when approaching the apex of a corner/roundabout.
With the new setup the car feels and drive like a BMW 3-Series, and I class that as a very good improvement... :xlol:
Standard Springs Rate for DC5: Front: 10kg/mm, Rear: 10kg/mm
Damping Adjustments: Affect both bump and rebound. Of course affect the rebound alot more than the bump.
Overall Free length travel of the front damper: 120mm (Remember this are Mono-Tube Dampers in a Dual Perch coilovers setup, so they normally have less travel than a twin tube damper because they have less by design and need less due to the Dual Perch construction)
Standard Top Mount on Coilovers: No idea... never tired it. But like anything I am sure we can make things fit if needed. The biggest issue you will have is the diameter of the shaft going through the top mount, and I am not sure what diameter is the damper shaft on the standard DC5. I am sure it won't be very difficult to make some type adaptor for the standard top mount if necessary... especially if this is for a race car.
