Finally after ordering FSD ,then changing to Bilstein ,then back to FSD due to being screwed around with availability my upgrades arrived.YAH.
Installed 2 weeks ago and time for review.
Gen 2 Koni FSD part no 2100.4039 , now with a 20% damping rate improvement over previous part no.s for gen 1,s .
SPC adjustable rear camber arms .
Fat Cat motorsports front bumpstops and adjustment plates .
(previously installed whiteline adj sway bars) with hd moog end links.
Overall install time was approx 8hrs ,but i have OCD and am very particular. Hah.
This car is now a totally different animal , the short sharp and stiff OEM responce to road bumps has been dramatically reduced , road noise has been reduced significantly, braking nose dive has been almost totally eliminated , steering responce is way better, so overall brilliant modification.The car now feels planted to the road ,turn in is more responsive ,but still have some slight understeer . Up to 80klms hr the car is way more comfortable and once over 80 the FSD seem to self adj to the higher frequency and become stiffer.
Many thanks to Lea Grimes ITT consultant Koni Nth America for tech info and email replies.Lea was the tester for both koni sports and FSD on the MPS platform and he has over 60k of road time using several FSD part no,s .
Fulcrum dealer for time spent on wheel alignment (rear camber now -1.0 deg ) previously -2.17 deg.
Shaik at FCM for tech info and linear bump stops.
Initial OEM wheel centre to apex of wheel arch height ,there was a height discrepency between heights (oem shocks built to a price where shit) that is now rectified with new suspension. Wheel heights front and rear are equal .
Front OEM bumpstops are very hard (no linear compression) rear OEM bumpstops re utilized as they add to rear spring rates and are fine to reuse.
Oem springs retained as Koni do not recommend using lower springs with FSD.
Problems encountered with install was zero, reused front strut bearings and spring bushes (24k) cleaned and repacked .Used anti seize grease to install struts to lower arm,re torqued all bolts to spec and scribed all strut top bolts before disassemble ,so as to install new FSD to as close as poss to original position.
Re used OEM strut piston top nut as it is higher and allows easier tightening , cut the OEM yellow boot retainer and modified to suit FSD stut , this allowed for reuse and position off dust boot.
The only issue was the Koni FSD instruction sheets ( they are shit) not very informative !
So for a very moderate modification price ,FSD $600.00 US ,Camber arms $200.00US FCM $ 90.00US and approx 8 hrs of your time , you will gain heaps of improvement and be as happy as i am .
