Need Spring Rate Specs

[lawler]

Hi i was just wondering if anyone has the spring rate specs for Whiteline R31 front springs and Im also after the spec of standard r33 gtst front springs?

[_Ryan_]

there is a group buy on r31skylineclub for some H&R springs with matched bilsteins, have you seen them? would they suit your needs? I had similar in my 31 with swaybars, was a good drive.

Na Im just trying to find out what the spec are. I already have white line fronts with kyb shocks and r33 front struts in the back on custom diff mounts

Lawler,

I think the standard front springs on a R33 from my calculations have a spring rate of about 3-3.5kg/mm......anyone know any better?

King spring low.

front 3.2kg/mm

rear 2.9kg/mm

Why are u running r33 springs in the rear when s13 coilovers fit right in with very little trubble.

s13 coilovers also fit in the front with some moderfercation (i.e diffrent parts)

also allows you to run r33 gts-t front brakes.

Yeah I had the same thought you did and brought some s13 hubs and arms then worked out it was to much to spend for very litle gain.

The r33 struts in the back is because a mate had 33 struts sitting there out of a half cut and just decided to give it a go and it worked well and when he stripped the car I grabed the whole diff, struts and arms it off him for my car for $150 because i wanted the 3.7 ratio and another set of arms to put my new bushes in

and as for the front end it has white line springs, kyb shocks r34 gtt brakes so I cant see the point in spending all the money to go to s13 front end. ill profer to spend that money on swaybars

Ah your front end is very simier to my old front end but i used r33 gtst brakes and had k-mac adj camber caster top hats. yep get some bigger sway bars, strut brace, cusco brake master cyl brace ($110 from powerplayimports under r31 house) and nolerthane bushes and it will handle realy good

can you shed some light on yuor rear end i.e pics im a bit confused

All the bushes are nolithain and yeah Im allready looking at swaybars, strut brace and the cylinder brace.

How hard were the camber tops to install?

As for the rear end well its a long story but a mate got bored and did it on his budget track build (I.e. under 4k build of pintara rb20det, ebay t3t4 turbo kit, r32 front brakes, weldy you get the idea) and it ended up in my car when the bushes went in just to see how it would go in my car

Im a bit hesedent to post photos due to looking a bit dodgy but the set up has done about 8k worth of driving, 4 track days and 3 drag meets with no signs of problems. tho there might be one in my build thread \/

Can you send the pics to [email protected] then.

as for the camber tops its pretty easy.

remove the front spring assymenbly fromt he car.

then atach sping clamps (they compress th springs)

compress the springs so the tension is take off the top hat.

then undo the nut in the center of the top hat and remove top hat.

install k-mac adj top hats re do nut release thenions on springs and reinstall

get wheel aliment

that easy

then to adj jack car up losen the 3 nusts and move the spring around.

Ok the photos are sent.

Did the camber tops change the ride hight at all
