R32 Gtr Traction Issues

[slaughter]

I looked at the title of this thread and thought "damn no traction in a gtr? wish i had that problem"

[whytry]

semi slicks.....nuff said

i have them on my gtr (300-odd kw), sticks to road like it should, and traction in 1st and 2nd is 'greatly' improved, and they are even 'good' (not the best) to drive in the wet, heaps of brands to choose from and are decent in prices.

but in saying that, with semi slicks they grip like no tomorrow thus putting more strain on drivetrain resulting in breaking things.

I would... But I just spent enough on 255/40/17 Toyo T1Rs that grip extremely well in my mate's 300+rwkw RX7 (the latest dyno tune and reading is higher than quoted above with mph to back it up and VBOX tune also - this car is on the cover of Fast Fours June issue), holding second gear and even third wholly in the wet. But in my car they are near useless in the same gears!

The car is missing/need replacing a whole heap of things, namely some arms in the rear which aid traction. $1200 later and we'll see how that goes (parts are on order now - front and rear end). If it doesn't work I'll move onto the transfer case replacement.

aahh yes i see, well that's easy, torque in ur's must be much much more than in ur friends rx7, try comparing it to his. and that was my next option ur control arms, suspension bits 'n' pieces might need replacing, don't forget the bushes

Thanks whytry. It's on its way to being sorted.

I'd say my mate's RX7 makes a bit of torque, once boost is added to a rotary they make gobs of it. The power band is actually extremely similar to my car!

Having been accused of being cynical, god bothering, and Today Tonight correctness, I am somewhat reluctant to dispell this 'urban myth'.

Weight transfer has nothing to do with soft or hard suspension springs or shocks.

Weight transfer in the acceleration/braking direction is governed by Centre of gravity height/wheelbase/G's acceleration.

Also, anti-squat geometry is designed to lift the car, causing an 'equal and opposite' reaction at the tyre, (ie more traction)

Physics has not changed since the earth was created.

Erol

Does that mean if his subframe bushes have rooted themselves, they wouldnt as effectively lift the car (anti-squat) so there would be less of a opposing force being exherted by the tyres towards the ground?

The thing i learnt about physics is that it is wrong, but almost correct, just that we havent figured out certain veriables that would make it correct..and if we did, we wouldnt need to worry about friction of the road as we could calculate how to make cars float...see string theory (make sure you have some head-ache tablets)...

So maybe check the subframe bushes??

One thing i learnt about weight transfer is that the easiest way to transfer 10 or so kg of weight to the back is to move the battery to the boot...

But I agree with Erol, the suspension will only handle the weight in its respective half of the car, but the stiffness will determine how it handles the weight, and the only way to change this is move the suspension closer to the centre of gravity (wheel base). This also explains why front suspension is sometimes softer then the rear, as there is usually more weight in the front half.
