Need Help With Traction Problem

[MJTru]

I own a r33 skyline reading from this forums i got a set of 15x8 with 5.5 back space, the tire is a 26x10x15 M/T. after getting these i had to do a brake down grade i used the 240sx brakes. does anyone know of any bigger size rims and tire that would fit even if i have to roll the fenders or even widen the body in the rear a little bit.

How about suspension I'm using k sport coil overs, with all stock arms, these seem a little to stiff. Can anyone tell me what kind of spring rate to use for drag racing.

has anyone use the ford c4 tranny yet I'm thinking of using this tranny because I'm close to destroying the stock OEM gear box gears are harder to sift and i hate missing gears. all 4 main rear sub frame bushing are damaged witch will work better aluminum or polyurethane bushings.?

Can anyone give me a site that deals with drag skylines or even a shop that i can contact.

I'v heard of people using the term pineapple what is that? in the drag world.

thanks again mate.

Bushes that go in the rear subframe to alter the angle (they are called pineapples cause a few of them are yellow and look like pineapple cut pieces). This allows you to alter the angle of the rear subframe for maximum squat (traction) or the opposite (usually for drift).

yes I've looked at the ones on the car and 3 of them are damaged is there any shop that you know of that will sell these bushings for drag (whit the right angle) and if i was to change the coil overs to a set for drag ones will that help.? if so what kind of spring rate would i need.?

I'm not running a LSD will this really help with traction 1000 is for a good LSD is it worth it?

thanks again mate.

yes mate i know it sound silly drag racing with the stock LSD. I had ordered one but the person at kazz couldn't find one for my car something about not having it stock and it will take about 4 weeks or longer. Today I'm going to change up the whole suspension.

I'm going to use the stock rear shocks should i change the front ones to.?

Now i will reorder the LSD should i get a 1.5 way or a 2 Way LSD.?

i have couple of adjustable rear arms but there on some 240sx I'll check to see if i can make a set of them work on the skyline.

does any one knows the spring rate i can try for drag racing.?

also with pineapple would work better for drag racing polyurethane or the aluminum ones.?

i have added a video of the car lunching. on the M/T tires. the other car a project of mine any help would be appreciated.

thanks again mate.

set the rear coilovers to the softest theycan go with the fronts stiff. the whole ass end will squat and sit the weight over the rear for better traction while the front stiffness will keep the front up bit higher. if its going to be a drag only car, then your best bet is to get 90/10 drag suspension.

shim up your diff to get full lock if you dont want to buy a brand new LSD ---> http://www.skylinesaustralia.com/forums/Di...Gt-t164288.html

the pineapples can be set up differently for different things --> http://www.whiteline.com.au/instruction/203a_KCA349.pdf

Put a set of standard skyline shocks in the rear and ditch the ksports.

mate just reading through your post , i also have a r33 gtst ,i got some custom 9.5 inch rims made ,but they are only steelys and i run 28 x 9.5 x 15 ..and i also have to run wheel spaces and when your running slick you need to do a big burnout before you lunch it ,as i didnt see you do a burn out thats all in your video.but i still keep my r33 gtst brakes as my rims fitted with the wheel space,what sort of power are you making and what times are looking at trying to get to.im just in the process of going back to standed shocks and springs as my r33 is blazing the slick off the line on transbrake

If your looking for a tranny ring als race glide ,ive got a c 4 in my skyline from als and ive got nothen but good words to say .

cheers

I'm so interested in the c4 set up with trans brake and stally converter. Do you have any pics of your setup. can you pm me with the shops phone number and address. or website please.

also how much did the whole setup cost you.?

to answer your question about why i didn't do a big burn out is because i was told that were not on a real drag strip the normal road will damage the M/T slicks. is the true.? most race are on abandoned roads.

one day i would like too get the cars in the 9's or 10's. After i get the car to hook good i will strip it down, no interior, roll cage

and best of all that c4 your talking about.

AMS performance over here sells the ring plate to fit a c4 on a 240sx. they use the front bell housing of a ka motor, now if i can remember properly the ring should be able to bolt a skyline r33 bell housing (Auto) on the c4 using the same ring. heres the link for the ring is it the same as yours.

the most hp i ever got out the car was when i used my friends haltec ps2000 we got 748hp rwhp. but now I'm back to the power fc with limiting afm. about 26psi on my AMS GT950R and I'm maxed out. i also spray nos sometimes.

Mate I'm very interested in your setup (c4) wondering if you can post some pics or even vids of the car it sounds nice.

thanks again for all your help

cheers.
