Tein Coilover question
Tein Coilover question
I'm getting ready to purchase a coilover kit and wanted some opinions.. im stuck between the tein flex series and the tein mono series .... heres what i want aggressive handling street use i dont mind giving up some comfort but i dont want a harsh ride quality either... please tell me what you would choose and why.. also what type of driving you would be doing.
ok was just reading some more in the forums about suspension and am open to any coilover manufacture... dont want to go over 2k for the coilovers. but want the best i can get for my money.. my style of driving is fast and faster... i love grip and want more of it but i also love kicking out the rear end.. i love the ride comfort it has stock but i can sacrafice some... now if you had 2g's maybe a bit more to dump on any coilover setup what would you get and why? please respond asap im trying to buy these this weekend or sooner would love to get it on when i get my new wheels on..
if i were to buy coilovers i again i would get the stance gr3+ due to it being able to do high speed and low speed bump compression adjustments and rebound adjustments as well. they are also a true coilover for the g35. i would also look into the buddy club, and k2 variant coilovers.
i would then dump it to the ground and get spc camber arms and toe bolts for the rear and 350evo camber arms for the front

have any shops at the top of your head who may be priced better than most? also which varient should i chose is there a way to find tried and true set-ups for those specific coilovers... thanks for all the help so far bro
I would not install Jic coilovers even if they were given to me, way too many owner comments logged on my350z since 03 that deal with the quality of the product and extreamly poor customer service. IMO they carry the short warranty that they do for a reason. Their are too many other choices that spec the same or offer much better qualities.
Well,..........I've been keeping track of owner comments since 2003 and you would be the first and only person that has discribed the Jic FLT-A2 on a 350Z as being "really comfortable", let alone post up in a thread there the OP want's comfort. I didn't write any of the following.

how is the ride? Stiffness isn't a problem, but a harsh ride would probably bother me. The stock suspension's tendency to "bounce" is somewhat harsh. I'm hoping to improve the handling and fix the bounce simultaneously with a coilover install.

hm, that's somewhat disappointing. I might have to talk to a few other people with FLT-A2s on other cars just to compare experiences before I make a decision.

I just tracked it yesterday at thunderhill and knocked about 4 seconds off my time. Their use of mild spring rates really soaks up the bumps which ultimately allows you to go faster. The shock adjustments really make a difference too. You can feel the difference of just one click. I'll write a full review when I have the time.

I'd think with the track oriented reputation they have, if they overheat then they're not very well engineered since their goal is all out performance.
The HKS's spring weights seem more neutral while the Zeal's is stiffer in front and looser in back. How would those compare?
I definetly want something track oriented/heavy duty, and well balanced. The HKS is less money, but I'm getting the impression they're more street oriented than track.

After about a year and a half my JICs pretty much started to fall apart. The finish on the springs started stripping off and the collars started rusting. Not to mention the damping on them was horrible little to no difference between full stiff and full soft. It didn't really matter anyways because the damper adjustment froze on them anyway. I will never ever buy another JIC suspension product ever.

I have driven 2 Z's so far with Zero 2's on the track, but not my own car yet.

The golden rule with suspension is to have as high a spring rate as you can have that does not go beyond the dampners ablity to keep them on the road on your given road condition's. Translation, excellent R&D affords the science on the inside to make higher spring rates work. Tein Mono flex has reviewed extreamly well on my350z, inspite of it's 14Kg/14Kg spring rates. IMO, register on my350Z.com and go to the regional forums that covers Washington state and post a request for anyone running the coilover.
KW Varient 3 has also reviewed well, however that setup uses a progressive rear spring that can put a dampner on your fun in agressive driving since it has a wide spread between the initial and higher final rate. You also give up full height adjustablity and if you need any parts, they are extreamly expensive.
If the Mono flex doesn't pan out for you I woud look into HKS hypermax III or Cusco Zero2. If you can afford them, Zeal's are known to be excellent.
