Is There Such A Thing As "factory" Lowered Suspension

[DaveO74]

Hey guys,

Im in the process of putting together the SK Gb setup for my 33 and so for have the complete Camber/Caster Kit and Pineapples (Not installed yet) and I was measuring up the ride hieght the other day to discover 260mm front and 350mm rear centre of wheel to guard hieght.

Now Ive always thought my line sits a little lower than most so is there such a thing as Factory lowered suspension on the 33 GTST???

Im fairly sure that I have factory suspension but not 100%

The suspension travel still feels fairly tight so I dont "think" it is past its use by date but again im not sure

Car is 98 GTST with 100k (Genuine with books)

260 mm front, I don't think so?

Standard (new) height is 375 mm front and 365 mm rear, settling 15 mm from standard is not unusual.

GTR V-Spec's factory suspension are generally lower than the normal GTR's. Check your VIN through Nissan FAST, might shed some light on the suspension.

Sorry SK typo meant 360mm

[Moodles2]

Was just pointing out there are different factory suspensions with at least 1 other model.

ur springs have sagged.

get new suspension.

Eh, 15mm in 100kk's isn't "sagging", it's well in the region of "acceptable settling".

Thanks SK looks like I still have a bit of time to get new gear. As I said earlier it still feels very tight and the car has been meticulously looked after since ive had it so I wouldnt think they are shot.

As long as they will hang in for at least this year ill be happy.

Now to just put the camber and caster kit on

Thanks again for the advice

true, 350 is still legal (at the limit), and 360 is well over legal for the front. if he wasnt gonna buy new stuff anyway, you'd probably get away with it. last thing u want however is to get defected for being a few mm too low with stock suspension because u just put in a full tank of fuel. so honestly there isnt a lot of point having stock suspension if theres still a good chance of getting defected anyway.

Unless I'm mistaken he's in NSW, we don't have ignorant Nazis doing rego here like you do in SA. We actually follow the ADR's, which means 345/335 is OK as long as it has a well designed 3" exhaust and the bump stops have been trimmed.

is it 345/335 over there? bastards. its 350/340 here, i thought that was universal for all states.

SA may have nazi's, but technically if the car is a few mm before 350, it is illegal and against the ADR's.

[Sydneykid]

There are basically 3 relevant ADR's;

500 mm headlight centre from the ground.

100 mm minimum ground clearance.

2/3rd suspension travel retained.

The 500 mm headlights is never a problem for a R32/33/34, because the engine subframe would be scraping on the ground if the headlights were 500 mm or less. Even standard length shocks don't have a problem with retaining 2/3rd the travel at 345/335. Then there are the options of lower profile strut tops and shorter shocks if necessary, remembering that 2/3rds is metal to metal.

The one that causes the most problem for R32/33/34's is the 100 mm minimum ground clearance, as the exhaust goes under the rear subframe. So a car with a 2.5" exhaust of decent design would have no problem with clearing 100 mm at 345/335. Even a 3" usually makes it, it's when you get to 3.5" and 4" exhausts that 345/335 isn't possible, there simply isn't enough room to fit that diameter exhaust under the subframe.

So the simplistic Nazis that say 350/340 is the ADR height are completely incorrect, there is no such measurement specified. The fact is I could have one at 320/310 that fully complied with the ADR's, if I used the appropriate parts, oval exhaust, short shocks and low profile strut tops.

ahk, over here in SA the eyebrow height is the first thing they go for.

it's actually 355 and 345 for the R33/R32. so technically it would be illegal. but if they dont check for that over there then ur in business.
