HAHAHA yeah ok. So in your personal opinion, Japan and its manufacturers are behind in the technology area? Yeah right..i see. I have a question for you:
If the Bilstein kits that are developed are absolutely the best thing the world has seen, why do they not do that number of sales in Japan?
Also, over 7kg the tyre is "outside its prefered range"? Well that would depend on what tyre it is yeah? (side wall strength, pressure, compund, temp?)
I am in agreeance completly that stronger springs, or excessively stong" springs cause a negative handling effect, but why do you bag out every single kit on the market that is not your own developed Bilstein kit? Bilsteins are a fantastic shock absorber. They are definately up there in quality and they work...but i can say from first hand experience that the Super Street Teins give my car a much faster lap time.
The adjustments on the Tein are simple...16 clicks that adjusts both bump and rebound at the same time. So, if it is cold or wet etc, i can simply soften the suspension to suit. If the day is warm, track temp is up etc, a firmer suspension will definately benefit. Its beyond me why you continue to knock adjustable shock absorbers? Is it because Bilstein dont do a cost effective Adjustable Shock? Just curious.
Thats my 2 cents.
