Is the variable diff set up worth it?

Question

Looking to buy first scooby after several years of rear wheel steering. No one will let me test drive sideways and have read of tendancy for scooby to understeer. Is this unjustified? If true, does the variable diff in the Sti RA solve this problem or are there more simple suspension mods that will change the balance of the car (without spending thousands)? Will probably be buying import STi 97/98.

The Type RA is just what you're looking for.
Torque split of 35/65 front/rear (or there abouts) so they drive like a rear wheel drive, or you can lock the diff forwards to approx 50/50 if the going gets tough

My STi RA is in the for sale section if you're interested

cheers,
simon

I've got a regular UK Turbo and it oversteers nicely, apparently the rear camber has been changed from standard, not my doing but its all I know since i've had it.

I think the UK cars are more front than rear wheel drive but my car steps out nicely, but it does sound like you're a good candidate for a Type RA!

I have a MY94 WRX and it def does understeer as a default. They do understear. Is still fun to control on the throttle though.

Thumbs up

When I first got my RA it had 16" wheels and major crap Jap tyres on it and the back must have stepped out about twenty times in the first two weeks (once at 50 mph in third, up a hill, going in a straight line and accelerating on half throttle ) Caught it every time, but it soon got 17's with Eagle F1's and now only slides when you want too .

The point is an RA (or R) is similar to a rear wheel drive car and could be right up your street. My 92 WRX (50/50 split) never got the back out, but then had only 260 BHP on 17's.

Enjoy..

T.

Many thanks to all who replied. Will definately be looking for an RA or R (as now informed) as it sounds like my ideal cup of tea! Will have to be patient till start new job though! Cheers.

I went from 93WRX to V5TypeR and the handling was muchos improved, never understeers now. You can dial in full negative camber on the standard scoobs (I did) and it helps but the typeR/RA's are the daddies, don't delay buy one today, you will never look back.
The only problem is when you fancy a change from a TypeR and there really is nothing better, so I'm keeping mine

Does this apply to the WRX type RA as well?

The WRX RA doesn't have the adjustable diff, but IIRC it does have a similar drive bias to the rear like the other RAs and Type Rs ~ you can't adjust it though.

Has anyone tried a Cusco 35/65 tarmac gear ?

I would like to have info on it before forking out the money or look at getting a box with the adjustable diff and ecu box and loom.

if the Cusco does the same thing then it's an easy fix

The easiest way to get rid of the understeer is to get the bump steer removed and the suspension set up properly. It is not an expensive job and it stops the front tyres wearing out on the inside edge too. The job costs a little more than one front tyre!
