View Full Version : D2 & G4 Coilovers...Opinions??
Hey everyone,
Just looking into the suspension while trying to workout prices and what not for the near future of my car, and at first i was considering the Cusco Comp-S, then realised i need to purchase pillow mounts extra and they are a fixed damper rate and in the end they end up being $2000+
Ive also now found G4 coilovers, which have a 36 way dampner and rebound adjustable monotube full coilover system. The setup has seperate height and preload adjustments allowing for optimal adjustment and allowing full strut travel at all times along with pillowball upper mounts or top mounts.
If anyone could give me some opinions and hopefully point me in the right direction, as im new to suspension mods and tuning.
Any help would be greatly appreciated.
Cheers.
Marc.

id like to know experiences too, as there is nothing Jap availble for my car under 2k....nothing under 3.5k too! Was seriously considering G4, as you can pick your own spring rates too, and 24 month warranty, plus fully rebuildable.
I'm sure lots of people will disagree but I'm a strong believer that the european stuff is where its at. H&R, Eibach, Koni and Bilstein have a lot of products available at reasonable prices even for Jap cars.
Bilstein is also factory fitted to EVOs, MX5s and Legacys.
If you're building a track car, JDM suspension is great but the euro stuff is a good compromise between road and track.

G4 also does an 8-pot set-up for dirt cheaps. A 6-pot AP/Alcon set-up is about $10k-ish and the G4's are less than 1/3rd that price (or something like that).
A few people have said that they (the cheap G4's) work pretty good. "Better than stock but not as good as AP's/Alcon 6 pots). Someone on Skyline's Aus. is going to take them to Targa Tas.
Personally I'm a little too scared to try their products (D2/G4) and would feel safer going for some quality brand name stuff, but that's just me.
Well as i said justin, any opinions would be great, but also if you can try and point me in the right direction as well, i dont know much at all when it comes to suspension and brand names as much as i know some of you guys.
:)
theres alot of comparison/discussion about these coilovers, people pretty much came to the conclusion that the damper setting does nothing (but make clicking noises) they had similar spring rates for vastly different car arrangements... the conclusion was, for the price of d2/g4's whatever, you would be much safer in the hands of tein ss (similarly priced), suspension isn't something you should skimp out on...
I agree Justin, I'm reluctant to use brands like D2 and G4. They make 4 pots and coilovers for the Clio because its actually a fairly common car in Japan (called the Lutecia).
Hey 4G, I would consider these setups before going to coilovers, you would be surprised how well it would work:
1. Whiteline Rear Sway, Dobinson/King Springs with KYB Dampers
2. Whiteline Rear Sway, Eibach Springs with Koni Yellow Dampers

I'd always go for coilovers before a spring/damper package as I like being able to adjust ride height to my liking. I've always done the spring/damper mod 1st and always ended up upgrading to coilovers, so best to save the cash for coilovers with both height and damper adjustment to start with (get it right 1st go).
I had Tein SS's on the MX-5 and they didn't lower the car enough for my liking so I had to replace the springs with shorter ones. If you do your research on the Tein SS's though you'll find that for the price they're pretty damn good and the damper settings definitely work (I often played with harder/softer on them. Full soft for skidpan made a world of difference, full stiff for track and a few clicks softer for street. Generally speaking, full stiff for track was only just stiff enough and full soft for street was way too soft.
apparently the justjap race car is using the g4 brake setup and they reckon its awesome

Of course they would, they arent going to bag out products they are trying to sell :P
But Clio im with Justin, it always works out cheaper to do it right the first time rather then go the cheaper option then pay again later on for further upgrades.
ClioF1 i told 4gColt to get a rear swaybar.
He's stallin hard.
Its the first mod you have to do one these cars due to the lack of rear swaybar.
Plus it only costs like $200.

Justjap sell a whole lot of cheap parts which are direct copies of other parts from Japan. IE: Brands which copy other brands (check JJR products on their site). Obviously there's a market for these cheap parts and it also makes sense to use cheap "disposable" parts on a race car (the MX-5 mania crew doa great job of it using cheap wheels + accessories).
Their engine damper kit for example is cheap at under $100 but are direct copies of the Section engine dampers from Japan. Their D1 spec quick release steering hubs are damn cheap too. I've had them on 2 cars now and yes, there was a bit of play/movement which is something you don't want to have on your steering wheel! IE: Scary.

I'm with justin. Too scared to use D2/G4 coilovers. I would always use a brand name product like Tein, Buddyclub, etc. Koni's shock with Eibach springs setup are ok... but driving some cars with them felt a little soft. So if the car is intended for track... all I can say is yeahhhhh they are soft.
Do it right first time right. I also reakon rear sway bar first! :)
I know a few people with G4 / D2s and they have yet to complain about them - however none of them are track junkies ....... for the money you have the ability to dump your car to the weeds, that'd be the drawcard for me. No way would i buy them if you intended on doing proper track work --- save another grand and get some Teins (ive HAs in the past and found they were a little stiff for daily driving ... each to their own).
Im still a big believer in the old saying, u get what u pay for.
Well its not really for constant track abuse, 98% daily driving to work and 2% (rarely maybe once or twice) will be on the track.
Ok iced and VTEC ill seriously consider rear swaybar first, but like i said i really do want to end up with coilovers in the car.

well get coilovers first... if that's a priority for you then do it. TBH... id do the same thing if I was you :). Just don't ignore the rear sway.
So far my car has been 98% daily.. and 2% track... and i wouldn't change my sussy set up for anything. Love the handling... even tho it hurts my back and ass... nothing a buddy club pillow can't fix! :D
I've heard cases of D2's... the actually shock piller thing snaped. I'm sure Zi has had these once in his life... if can recall him telling me. I asked Indy about these coilover (D2's)... and lets just say he didn't look to happy that my mate was even considering them.
Sometimes I think coilovers are overrated, but for trackwork it will generally mean stiffer spring and damper rates which is more suited to that type of thing.
Ride height adjustment is good, but its main purpose is for the ability to cornerweight and set the f/r balance rather than get the looks right.
I'm going coilovers in the Clio mainly because its the only way to get into a monotube Bilstein damper. For the Lancer I'm putting in springs and shocks, I just couldn't justify $2k+ on coilovers for a car that cost me $5k.
iced has also tracked his setup, so I'm sure he has some good advice to give.
Hmmm i do see some valid points being made.
Bloody hell, i didnt realise that it could be such a pain in the balls to find some decent suspension.
Ive thought about it....i will allow $2000 - $2250 for suspension, ANY ideas guys, ive already got the front strut brace (i know it doesnt really do that much) to work with. Please help as i said earlyier suspension isnt my area and i dont know too much about it, as for the installation i can get it done private so that budget isnt including installation costs.

Stay away from g4's and d2's.
Try the HSD (HD Systems) coilovers - they're a jap brand and have had personal experience with them - very impressive for the price. Failing that, perhaps some TEINS?
Buy Cheap; buy twice!
I've got HSD coil overs in my car and i haven't had any issues with em
IMO they are awesome for the money
HSD do look good thanks for the tip, but they arent available for my car, EVO's only :(
Who sell HSD's locally in Australia?

www.otomoto.com.au (I think)
Thing is, like he said, there is nothing available, only G4/D2. There are a few competiition drift cars using G4/D2

dude!!! my mate is getting some Tein Flex custom coilovers from Fulcrum for his DC5, for like 2800! So surely if you ask the right people you can get for cheaper. I know Bel Garage is able to do some alright prices on Tein coilovers. Indy was telling me how similar Tein Flex and Tein SS are... there's just little differences that make it slightly better!

So true so many people get caught up in the whole "i love being able to adjust my shocks for the road track" etc but the real advantage of coilovers is being able to set the cornerweights of the car which if your not doing this before your going to the track then you might aswell just have koni inserts and whatever springs.

That is sooooo very true! When I first got coilovers... I didn't understand the issue of balence. I went for a hard drive one night... and was understeering alot when entering a corner. I then told Indy... and he told me I was to lower the front another 3/4 inch or so. So I did... and it's much better. Could be slightly better tho.
