D2 Suspension

[dxbgts33]

Just installed my new RACE TRACK spec D2 coilovers on my nissan gts r33 98 model (only drive it on track days), took it down to the track and the car literally sticks to the ground, huge improvement for a reasonable price.

I found that the harder I adjusted the damping the more stable it got on corners. The Maserati behind me was all over the track going off the chicanes it was a laugh. But my car cuts off so given up after a few laps.

Rear: 3.0 turns from hard

Front: 2.5 turns from hard.

Will try harder settings next time.

moved to suspension.

are these the suspension u can buy on ebay for $1000. because if they are TELL ALL. im looking into them

any problems on install or wateva?

[dxbgts33]

Very easy to install, maybe 1 hour work. If you're in australia there are many dealers in your area. I suggest that rather than buying on ebay. Safer.

I dropped the suspension by about 10cm (4 inches) really easy

[r33cruiser]

would u compare them to tien? or other high priced brands?

Where is your local track. What other mods do you have and what tyres were you running? I only ask as i find peoples opinions on suspension vary greatly, so to me the real indicator of good suspension is the pace it can be hurried around a track. I drove a guys neat R32 GTSt at Eastern Creek a few years back. Had more power then my car, no speed limiter and about the same tyres. I have better brakes...and i was able to circulate almost two seconds quicker in my car then his....he jumped from mine wanting my suspension as whilst his was way firmner mine gripped a lot longer.

So what feels tight and grippy may not really give good traction, even though it may be to the owners liking or what he feels handles good. LOL hanflign does not equal traction

i had d2 in my r33 and for the price i paid. i found them pretty good as entry level coilovers. but they were pretty bumpy/stiff on the street.

[r33cruiser]

thats good tho micheal. i prefer the bumps to boaty suspension.

i would also hazard a guess that it felt grippier because it was lowered by 4''

ok well 1st off what were u running b4? of course it is gunna feel like the bomb if u've just been rollin round on stock suspension

again what tires, if there not the same as u ran on ur previous setup then u may need to factor that in

how did u change the geometry of the car (camber/toe/castor) also as its been mentioned dropping the car 100mm is gunna help feel and performance

also be carefull comparing to other cars on the track cause driver skill come into it ALOT more than the car, i've beaten 400hp GTR's around a track in my old car with 150hp and busted ass JIC's

also u list ur prefered settings for stiffness and say that u wanna try stiffer, were u being timed? and did u compare times to setting to find the optimum?

i dont doubt that ur car does indeed go better with these coilovers than ur std suspension... however these cheap coilovers D2's G4's and ISC's simply do not have the R&D put into them that they need. they use overly stiff valving and spring rates to make it 'feel' faster and more fun to drive, but infact if you push it to the limits they simply cant provide the grip that a quailty product can. i have custom bilstine coilovers all round on my car (track only) and i love them, they're softer than my previous jap spec coilovers but provide much better grip through both the tight twisty stuff and the long sweeping bends; admitadly it is too soft for drifting and as thats the direction that i wish to take the car they will have to be rebuilt to new specs, a costly and time consuming exercise, but necessary if u truly wish ur car to handle

basically what i'm saying is they're good, an improvement over std, but there is alot better out there and personally i wouldnt touch them (quality products will also last longer)

well gentlemen, let's not overcomplicate things.

R31_pwr how do u know that D2s don't have R&D put into them?

comeone fellas, we all know who the big players are and many people fall into the trap of paying the extra 1,000 bucks. there are people that bash teins, ohlins etc..I know a guy who suggested buying USD 20,000 suspension saying they were the best. By the way D2s are not cheap, I think they are reasonably priced rather haha..let's not get corporate...but anyway who knows I probably will try the others as time goes by and the track gets more serious. By the way we're doing trackdays in Dubai at the Dubai Autodrome.

Roy I think you were faster due to skills maybe, but let's not forget NA are generally lighter than the GTSt. Also luck plays a role as well as he may have slipped for a split second which accounts for the time difference.

I think my current Marshal KU17 92W R16 are ok but I might need to upgrade to steel re-inforced side walls. I am working on the car, have been for 4 months now and there always seem to be improvements to be made.

We swapped keys, he drove my car for a session and i drove his. We both agreed that my car was a little more dull but had more grip and the times it did showed. Hios car was tighter and dartier, but less grip and slower. Could have been tyres, alignment etc etc. So, meh, not sure how much water my point holds. Before after times etc always make a good indication rather then seat of pants

[R31_pwr]

i didnt say that they didnt have R&D put into them (any new product has to) what i am saying is that its not suficent. also the build quality is poor, i have seen the mounting brackets (S13) snap in what could be deemed as a small incident (car got about 1 foot of air)

these coilovers are built in china on a tight budget and it shows, unfortunatly most people that would even consider fitting these to their car would think that they're the ducks nuts cause all of a suden its a stiff, jumpy and 'feels' exciting which 'feels' fast... it took me a while to learn that a boring ride/drive is often alot faster

If were he runs is anything like the billiard table smooth Bahrain track, then he could almost get away for 4 bits of 4 x 2 instead of springs and shocks.

Sorry to dig up an old thread... but can someone send me instructions or tell me how to make all the different adjustments to the suspension as i think mine have previously been adjusted wrong...

Cheers

[STATUS]

imagine how good the car would handle with something decent......

[belo]

I know.. but they came with the car and i dont have the $$ to replace them with something better at the moment.

Anyone?

Thanks
