Traction Probs with rwd Cars

[Bleck]

G'day all,

How does every else with >200rwkw cars go for traction?? I have a daily driver R33 gts-t with 210rwkw and find it very difficult to get traction on the street. In first and second if I put the foot down, I get wheel spin. I could do a quicker quarter with a stock car at the moment.

Current mods that could be causing this:

-Twin plate clutch

-Hankook Tyres (cheaper)

-Tein coilovers

-265/35-18 tyres

I have a few theories:

- obviously softer (read: more expensive) tyres would help

- softer rear suspension may help????

- Would a narrower tyre (255/40-18) help? ie. greater weight per square inch of rubber on the road

I'm assuming that I'm not the only one with this problem and want to sort it out before I upgrade the turbo. No good having 260kw if you can only use it on the dyno. As it's a daily driver I'm not looking at spending too much on the tyres. Hoping to keep it under $500 per tyre and with relatively ok life.

Cheers,

Bleck

I'd go for the rear suspension being too hard theory. I believe I have the same problem as I'm running Kei Office coilovers, and there is bugger all traction 1st, 2nd and sometimes 3rd. I'm looking at getting a set of softer springs made up for the rear though as many people have mentioned before that most Japanese coilovers spring rates are about twice what they really should be for the roads in Australia and New Zealand.

well mine doewsnt have anywhere near 210kw but i noticed that with the old tyres(bald) it was very silly trying to get traction on the street coz they just spuin everywhere, i was in the same boat 1st 2nd was just spinning, however i went and got osme new tyres and they were 245/40/17's bridgestone Grid II i have to say these are better than the 255 tyres that i had on it previously, much better traction, 1st only spins a little with 2nd on spinning on gear change then she al go fromthere. maybe try different tyres, i got tein adjustables on mine and i have put em lowish, i still ran 13.5 with my shitter dude so i reckon u should be able to do at least that. twin plate may be a back foot step, although nice and strong, i think the ability to slip them isnt as good as your average organic shit one like mine

go get some decent tyres.

[DoughBoy]

Tyres for sure. With a HKS 2530 (220rwkw) + 265/35/18 Dunlop R rears I could only spin them by popping the clutch or taking a corner pretty fast and booting it midway. That was with ultra stiff HKS Hyper D suspension.

go get some decent tyres.

:werd:

I can't understand why people put crap rubber on cars with this much power....:confused:

More compliant springs will also help with maintaining rubber on road contact.

[B-Man]

Pineaples or Alloy Cradle spacers help too , I hear.

B-Man needs launching traction .....

[SATO GTS]

try putting in more positive camber so that when the rear of the car squats under hard acceleration there is more tire contact on the road then now with the standard settings..

i am not sure what the camber setting are on a lowered 33 or standard height car but when they get lowered the rear camber will go higher into the negative setting then there should be..

even a 1/2 to 3/4 positive camber change will not effect tire wear..anything above 1 degree will ..

or just go to a solid rear end then all your problems will be solved.. hehe go the 31's

[DentonR33]

I have exactly the same problem, 212rwkw, 2530,

Firenza 265/35/18, and if i put my foot down at say 50km/h in 2nd gear it will lose traction from 70-100km, first gear is unusable

[franks]

well i guess its time to put some 300+ sized baby's on there

[benm]

The joys of having -TOO- much power ahhh I wish...

[2BNVS]

i had the exact same problem when i had my stockies on and i only got 172rwkw since i purchased my rims (19x8) with 265/30 tyres on rear thats stopped lol their freakin heavy bastards, but yer with stockies like mentioned 1st gear a waste and 2nd gear still spinnin.

cheers...ben.

186rwkw, <10,000km = no wheel spin, do 67 laps at wakfield and its wheel spin happy.

Can't go past a good set of tyres regardless of the size.

[09ONE_32]

Yep, not always tyre size that is most important, quality. A good get of 225's will easily outperform a pretty dodgy set of 255's.

with ur 18s, the sidewall is thinner so not good for traction. soft sidewall will help, but not good for cornering. It u want better traction, tyres, suspension has to be softer, similar to stock, and some decent camber kit at -0.5 deg

[knore]

Ive got 166rwkw and i spin my dunlop 255/40r17 fm901s like they were spacesavers

They are mega old tho,

Getting Falken RT215 255/40R17 SemiSlicks next so i cant wait to see what happens

-Ive got full whiteline handling kit, strut brace and tein suspension/springs

[DentonR33]

Ive got 0 neg camber on the rear, pineapples set for traction, and a set of brand new bilsteins with lowered pedders springs.

TRACTION ISSUES. I also/STILL get axle tramp

I might go decent 255/40 instead of 265/35, more sidewall more traction?

what decent semi comp tyres come in 18" that arent 600 a tyre

[KamikazeR33]

id go for the suspension issue first

then go for tyres

my mate has a s14 with over 400rwkws and threw my old tyres on it n it still had good traction. he has his suspension setup for drag also

[Guest INASNT]

Thats the problems u have with small turbos like the 2530, they come on boost to early and hard in the rpm range causing wheel spin then die up top.

[Jimbo2000]

i have been driving a 205rwkw 33 for a long time and now a 223kw with no real traction problems USING HANCOOK TYRES.

they are shagged and i need new ones and i can still get the power to the ground.

i beleive the susp on my car is not stock and thats probably the difference.
