A brief tutorial on suspensions:
A number of suppliers claim mono-tube struts and shocks are superior to our twin-tube design. This is just not true! Quality valving and structural integrity are all that matter, so don't get sucked in by such claims. Furthermore, high pressure gas dampers reduce ride quality on the street, while not offering any improvements on the track. TC Kline/Koni dampers are made to our specifications and have special fluid which will not foam, even without gas pressure.
Second: High spring rates are great with fresh tires on a smooth track, but in the real world,SUSPENSION COMPLIANCE IMPROVES TRACTION.When conditions are not ideal, which is 90% of the time, a softer suspension will allow the tires to work without being overloaded.Our philosophy is to install the softest setup possible - WITHOUT COMPROMISING LAP TIMESThat way you will be faster for longer, because your tires will not degrade as quickly, and your car will perform much better in less than ideal conditions.
It takes many years of experience and continuous learning to fully appreciate this. - TC Kline
