Track Prep FN2R

[lukits01]

Hey lukits, you seem to be against japanese made coilovers, any reason(s) behind your mindset?
What is the difference between rebound and bump adjustment?
Are there any advantages for progressive spring rates compared to fixed spring rates? What is the best way to reduce roll resistance? I noticed you installed a rear sway bar, how does help to the fn2r as I feel that the rear stays pretty flat through corners in stock setup.

mmm nothing technical really, just never seen one that I've been impressed with, seen a few too, HKS/Buddyclub/GReddy/Spoon/Toda/Cusco they've all been pretty rubbish with their setup.
A few of the top of the range Tein was alright, but still nowhere close to the range of capabilities of the European offerings.
In general, silly spring rates and overdamped to compensate for silly spring rates.
So what you get is a car that can't handle bumps and just too stiff to allow any kind of weight transfer.

theoretically progressive spring rates gives more comfortable ride but sacrificing response, they need the shocks to be valved to suit. So you shouldn't change springs with shock absorbers valved for progressive spring rates. Progressive springs are best for road use, a GOOD (e.g. hypercoil/swift/eibach) linear spring for performance use.

also theoretically a slightly over-steering car is always the faster car, the stiffer rear swaybar is there to help lift the inside rear wheel, transferring the weight to the other 3 wheels.
