i was out the other night after it had been quite rainy and for some reason at every roundabout or tight bend i felt like i was on the edge of understeer even at fairly lowish speeds...only ever noticed it once before but i was pushing it quite hard then...

i know imprezas are prone to a bit of understeer, but why havent i really noticed it before...? cant just 'come on' can it...?

In our '02 WRX at the 'ring, taking it steady as it had just rained so the track was greasy, we had a hairy understeering moment. Not sure how fast it was but alot slower than in the dry, and in the dry and the pissing rain it wasnt getting anywhere near understeering. Its probably the greasyness/tyres that effect it.

totally agree, have found this also

Me too ('51 WRX). Bump steer mod required?

My99 not found this at all. Maybe its something to do with the tryes, the term handles like its on rails comes to mind.

Gonna hit a tree now I've said that

subarus are $hit in the wet

I think you need to find a better version then mate. Mine handles perfectly wet or dry.

I wearing Toyo T1S's on the front, I'm thinking or putting Michelin Pilot Sports all round when they need replacing.

phelpsa

Go for Goodyear Eagle F1 GSD3's all round. These are known to be one of the best all round tyres around.

had an RB5 and now a P1 and one of my mates with a WR1 says the same as me, not exactly bad models mate.

Im running pilot sports and would recommend them, hated the T1s

I find the T1S pretty good in the wet!!

I've got Pilot Sports on the back and they wearing really well so I'm gonna go for them probably.

stilover

I have Pilot Sport 2's on my STi. Can't recommend them enough. Fantastic tyre

i get it quite ofter in the wet, lots of tight roundabouts near mine....

Just make sure your aware that this can happen,

Its called getting to know your cars handeling characteristics.

Im pretty far from the best driver in the world, and mine is on the standard tyres Bridgestones i think, but im far from knowing how to really push mine hard...

Maybe some of the track drivers can tell you more about this,

Ps, mines an 05 WRX for what its worth

hmmm, ive got a 02 WRX with p zeros on...just felt really greasy on every roundabout...shook my confidence a bit...maybe the pressures are a bit low...? how much of an effect could that have...?

I got rid of most of my understeer on my UK classic by.....

1. Having a good set of tyres. Not too hard. I use Goodyear Eagles which are very, very good in the wet. There are other makes too.
2. Uprating the springs to Eibach pro sport.
3. Having a whiteline rear anti roll bar and drop links.
4. Getting Roger Clark Motorsport to do a Geometry/allignment set up for fast road use.

Very, very happy with the result.

Done a few basic low cost mods myself to try and rid my wagon of understeer...haven't touched the springs and dampers cos I LIKE the way it rides. But basically, my ARB drop links at the rear were knackered and the fronts were on the way out, so I changed them all for Whiteline heavy duty alloy jobs. This had an immediate effect, makes cornering neutrality/oversteer appear much sooner and more 'clearly' if that makes sense. Still had a tendency to plough on in a straight line in the wet when pushed, so looked a bit more into some of the Whiteline testing and tried their optimum pressure settings for the tyres - 37psi at the front, 32psi at the rear. This made yet another leap forward in getting rid of understeer.

Next step is to try the 22mm adjustable rear ARB with some heavy duty mounts and see how that goes. The theory sounds right, so we'll see how it goes in practice. Also I'll be looking at getting 1 degree of neg. camber dialled in on the front and a bit of toe-out on the rear, think it was 1mm but I'll have to check. This should also help the front to do more of the work of digging in and turning, leaving the back a bit more controlled by the throttle.

brihoppy

all sounds a bit complicated...i suppose there are places you can go to get this done...?

Nick Read

Yeah - you're in the middle of the country so it can't be hard to find a Scooby specialist round your neck of the woods. To be honest it's all suspension work so it's not as if it needs a specialist to do it though. Changing ARB links is a case of undoing a couple of bolts and putting the new ones on, pumping up tyres to correct pressures it not exactly tricky and setting suspension geometry is quite straightforward for most garages. It can all be done with the car on a lifter and doesn't need any specific knowledge of Subarus. Start with the heavy duty ARB links and go from there.

pappasmurf

...getting four wheel geometry/allignment done for fast road use by someone like Roger Clark Motorsport makes a big, big difference. Don't go to a Subaru dealer they are generally clueless. Proper geometry makes an astounding difference.....one of the best..if not the best £120 i spent on the car.

the standard bridgestones on my classic were pretty bad tyres ,,it understeered a lot when pushing on ,,i had new wheels and tyres on it ,,pirrellis iirc and it did improve but it was always an understeerer when pushed.

Keef69

I was about to book in for a geometry set up as I hated the understeer on mine. Had pirelli's then Bridgestones and there was little difference. Then, having read a lot on here and other sites, I changed to Eagle F1 GSD3's all round. The first 500-1000 miles is weird, but when they settle down, WOW. Whether it's wet or dry, I just go round the roundabouts now, instead of sliding to the outside!Never realised the right tyres can make so much difference!

Sounds like this Eagle F1 GSD3's can be the first step. I also had understeer and it came completely unexpected. Took a curve just like it would be dry, but it was a bit wet. Still run on std Bridgestones, not too good in the wet. The Michelins sports were also recomended here. I'm not due to tyre change, but next year will come to that, so I know what to get now

i had oversteer round a roundabout on friday night when it was greasy. I wasnt powering round it just caught my attention that it oversteered when i was expecting it to understeer. Its a standard MY04 UK STi

brihoppy

im right in saying though that understeer in a car serves absolutley no purpose whatsoever...?!

bioforger

iTrader: (1)

Well its just built in for safety thats all. Most novice drivers can handle understeer better than they can an oversteering car I guess.

automodellistagt

its a lot easier to correct and you can do a lot more of "it" then oversteer without getting into too much trouble. The older generations among us will be better at correcting oversteer since you grew up with oversteering rwd cars like escorts etc. Us young'uns have a tougher time since we dont know what it "feels" like till its too late

Jonesy24

£500, ProDrive spring and settings and it will drive like a different car!! Many people spend their money on straight line speed and go much wider than me in the wet...........I love roundabouts in the wet!!! Car tucks in with controlable drift.

mg driver

i know have the newer toyo T1-R's all round and once scrubbed in they are by far the best tyres ive had in wet or dry and they replaced michelin pilot sports.In wet conditions where the pilots would go straight on the toyos just grip and go .
