MK3 Coilover info

MK3 Coilovers:


Cusco:

Comp S: Features 16kg/mm front 10kg/mm (rear) spring rates, a non-adjustable damper and optional upper pillowball mount. This is a high quality coilover, but lacks almost all features. These are quite firm, and best suited for aggressive street and track driving. Prices range from $1125-$1325 (with or without pillowball mount).

Zero-1: Features 18kg/mm front and 11kg/mm (rear) spring rates, a quality non-adjustable damper, and optional pillowball mounts. It can be adjusted for height without affecting spring preload. This is a high quality unit and is best suited for serious canyon and track driving. Prices range from $1325-$1525 (with or without pillowball mount).

Zero-2: Features 18kg/mm front and 11kg/mm (rear) spring rates, a quality 5-position adjustable damper, and optional pillowball mounts. It can be adjusted for height without affecting spring preload. This is a very high quality unit and is best suited for serious canyon and track driving. Prices range from $1650-$1850 (with or without pillowball mount).


HKS:

Hipermax II: Features 14kg/mm front and 6kg/mm (rear) maximum progressive spring rates and a very high quality 30-position adjustable nitrogen filled damper. This is a quality unit, but is prone to surface rust on the threaded portion of the body. This plush coilover is best suited for touring and drag use. Priced around $1800.


JIC:

FLT-2: Discontinued... Features 18kg/mm front and 10kg/mm (rear) spring rates, 15-position adjustable nitrogen-filled dampers, and can be adjusted for height without altering piston stroke. These are a lightweight coilover suitable for track use. Priced around $1600

FLT-A2: The older units feature 14kg/mm front and 10kg/mm (rear) while the new ones are a bit softer at 12kg/mm front and 9kg/mm (rear). They also have 15-position adjustable nitrogen-filled dampers and can be adjusted for height without altering piston stroke. They are best suited for aggressive street driving. Priced around $1625.

SF-1: These have been discontinues but are still in stock at many stores. They are just like the FLT-A2s, but are not adjustable. Typically priced around $1325, you can find them on blow out for less than $1200.


Kei Office:

GU: These discontinued coilovers had 14kg/mm front and 12kg/mm rear spring rates and were designed for the drifter. They had 4-position dampers and could be adjusted for height independently of spring preload. They typically sold for $1800.

GX: These coilovers have 14kg/mm front and 10kg/mm rear spring rates, have adjustable dampers, and can be adjusted for height without affecting piston stroke. These are best suited for the drifter or autocrosser and sell for around $1700.

TE: The entry-level Kei Office coilover, these do not have adjustable dampers but feature 16kg/mm and 10kg/mm spring rates making them suitable for very aggressive street driving and occasional track use. They sell for around $1475

XR: These discontinued top-of-the-line Kei Office coilovers have been replaced by the XT and have the same spring rates and damper specs. They sold for $1800

XT: The XT's feature 16kg/mm and 10kg/mm spring rates and 16-position dampers making them a good choice for the aggressive canyon carver and weekend autocrosser. They are also popular with the drifting crowd. They tupically sell for around $1800.

XT-alpha: These have the same specs as the XT, but also feature helper springs which keep the tire on the ground on rougher terrain. This is the new top-of-the-line Kei Office set-up and runs for around $2125.


Silkroad:

RM-A8: These dual-height adjustable aluminum coilovers have 18kg/mm front and 10kg/mm rear spring rates. They have 8-position dampers and are suitable for the serious enthusiast. They used to sell for ~$1325, but now that they are better established they've raised prices to ~$1450.


TEIN:

Flex: Perhaps the most popular coilover for the MKIII, these coilovers have a street-friendly spring rate (12/6), 22-position dampers, and are adjustable for height independently of spring preload. They also have an option for electronic adjustment. They typically sell for ~$1500

HA: Discontinued... These have the same springs as the Flex, but 16-position dampers instead of 22. They didn't come with pillowball mounts (but were often added separately) and were compatable with the electronic adjustment. They sold for ~ $1050

HR: Discontinued... These were a non dampening adjustable version of the HAs and sold for ~$950.

RA: Once a popular coilover for the road race crowd, recent competition has this coilover headed towards being discontinued. With 18/10 spring rates and a quality dampener, it packed a performance punch but the lack of dual ride-height adjustability is leading to its demise. They can be special ordered for ~ $1650

SS: A close second in popularity to the Flex, these bargain priced coilovers have more of a sporting edge with 16/9 spring rates and 16-position dampers. These are like a racey version of the discontinued HA and priced under $1000.


ZEAL:

Function B6: While these coilovers pack the features of units costing $600 less, their quality is unsurpassed. These are suitable for the aggressive street driver and road course lapper with 16/10 rates (14/10 "soft" rates available). Priced around $2300

Function S6: With the same spring rates and features as the B6, these higher end versions have lighter springs and a full aluminum body. They sell for around $2650.

Superfunction: Fully customizeable with separate rebound and compression dampening and your choice of spring rates. These are built to order and carry a $4500 price tag. Rare is an understatement...

Hey, now I dont know which one to go for, Kei Office or Silk Road, I mean Silk Road has a stiffer spring rate, but Kei Office seems to be better quality, really if money was the problem I would go with Silk Roads but for my baby money isnt a problem, but for other things it is,lol. Which ones do u recommend??? Which ones are easier to get rebuild kits and what not???

You can order Silkroad with custom spring rates, but you're right Kei Office is built better. Both companies are setting up shop in the USA so by the time you need to have them rebuilt you won't have to worry. At this moment, everything gets sent to Japan for both companies, but neither one is difficult to get rebuilt (they just take just 2-3 weeks)...

lol dude I didn't know Silk Road was from Japan, thats pretty kool

It doesn't get any more JDM than our spec sheet :lol:

LOL cool beans

Jeff, do you have any info about the springs, spring rates, etc., for the old Ohlins coilovers? Or know of any way to tell from the springs themselves? I don’t know anything about the springs I’ve got on mine, so any info you could share would be much appreciated.

I tried to get info from them, but Ohlins USA never sold them and did not have any specs (and cannot rebuild them in case you were planning on getting a set from a japanese auction). Ohlins Japan never responded to my emails.

I'm all about my Tein Flex setup. It'd be cool to have some Cuscos-not overly expensive, great quality and uncommon. I was told by an SP Engineering sales rep that JIC coilovers are made in Korea-sh*tty. They aren't my style, anyway.

We just added Buddy Club to the site :eusa_hand

We just added Buddy Club to the site :eusa_handIs that smily used in the proper context, Jeff?

Heh, I don't think that was the one I intended

I've tried to use a couple that didn't come up as advertised. Maybe that was the case.

i'm running the cusco comp s coil overs but they are getting a bit tired now and i am going to change them for some leda coil overs. i pestered them untill they custom made me a set up with 2 1/4 inch springs because there are lots of spring choices available in that size. the shocks are have a 22 way adjuster on them and are cheaper to rebuild than to buy ordinary supra shocks.

Good info man.

how mauch did you pay for them hagar??? i need a new suspension set up.. the only prob i find with coilovers is if you get 1 corner out of sync by about 2mm in height the whole car will handle like a bag o grampa's finest compo "shit"

£1160 including sending off my old suspension so they could measure them. i ordered them at the beginning of the racing season as well so they took 2 months to come back as well. i will swap them all over and put on my white line antiroll bars and poly bushes when i get some time off work next. for a complete rebuild of a shock is £50 each.

Ive got a full set of KYB adjustables in the shed. And have seen coilover kits on ebay.
These shocks are full of gas and im not sure about welding the threaded section to the shock.
Has anyone done there own and did it weld ok?

can you not take out the gas insert first before welding. most of them come out as a single unit. however if they are not the first sign you will get is the hiss of the gas escaping and it will be too late then.

personaly i wouldn't weld them the gas in them is hat such a high pressure and your going to introduce mr heat from the welder.. you'll be looking for your arms in next doors garden

coil overs are a different type of suspension. the bottom mount for the spring is adjustable and not fixed to the outside of the shock absorber body. because the outside of the shock body is threaded and this means that the cars ride high is adjustable either upwards or downwards. the springs are normally of a smaller outside diameter so this means larger wheel and tyre cominations can be fitted as well. the shocks are generally adjustable as well from stiff to soggy. some have 2 adjustments on the shocks but they are well pricey.

here is a piccy of one of ebay today. the springs and top mount aren't on these but you can see how much adjustment is on the body of the shock absorber.

alright I get it now. I appreciate the input.

Nice write-up. This post is quite informative.

which coilovers would you still be able to use the tems suspension? going from sport to normal and all that. cuz sometimes if i ride on sport too long the ride is rough and its uncomfortable to drive, so i switch back to normal. im thinking about going with tien. are they any good? my car would look bad if it were lowered.
