Just got the car out of winter hibernation (storage at the Toronto Lotus dealer) last week since the dry weather has returned. What a rush!!
The car has now turned over 8500 miles and runs like the first day the KOMO-TEC 280S kit was installed. The Kit has been flawless from every point and has over delivered on every promise it made.
The only complaint I have, is the amount of rubber the kit has removed from my tires

If you stand on it, without the Traction Control on, the tires light up all the way through 2nd gear once they break traction.
Picture the look on the faces of the Porsche drivers when you pull by them on the straights at the track

...Worth every nickel spent.
I have considered the new 300S upgrade but, at this point, the current performance is beyond my driving capabilities. The One item I would recommend if you do go with the KOMO-TEC upgrade is bigger brakes. Because of the additional speed in which you are coming into the corners on both the short and long tracks....bigger brakes are next on my list.
