TRD shocks and springs

[Uzelac]

NoHachi Wrote:No, the forces on a 8kg spring result in a compression stroke of around 75mm. So you need around 75mm between the position of the spring at rest (with sprung+driver weight) and the top of the strut. Your solution leaves too little compression stroke and will leave the spring free in rebound. Check your numbers again and you'll see.

Whats wrong with my math? Look pic4.
Raise shock for 15mm (bigger spacer (35mm), smaller cut (25mm)) and leave perch at same position.
You will get 75mm of comprssion and 72,5mm of extension for HTS 102 damper which have 147,5mm of travel.
What is wrong with that?

If the measurements were 100% accurate, then the best solution would be to cut 60mm from the top of the strut, above the perch and leave the perch where it sits. No spacer needed.

Stock AE92 have 160+ mm of travel, but SS Konis (Koni sports for AE92) and HTS 102 have just under 150mm. 50:50 proportion for extension:compression makes it around 73mm for both.
