STi steering issues.
#32
It's fascinating to hear how much difference the combinations of tyres, wheels, offsets etc can make, I didn't realise. It sounds to me that I would be better off trying the 18s again on P-Zero Neros (if I have read you guys correctly)?!!

Before you buy some different tyres, take your car to Powerstation, and get them to setup the alignemnt.
Had mine done today and the difference in the car is amazing.
The rear camber/toe was just about spot on, with only the n/s rear needing a slight tweek on the toe.
The front - one wheel toeing in and one toeing out, and camber also way out.
Now, I had no issues with the car beforehand, the wheel was nice and central and no strange tyre wear.
After the adjustments :-
The first thing I noticed after coming off the ramp was how easy the wheel felt to turn from the straight ahead positon, compared to before.
Secondly, some fairly wild movements in the wheel under power with lock on, which previously I had put down to the front diff, have been drastically reduced. Still there, yes, but much more subtle.
Thirdly, the car feels much more stable and planted to the road at speed and when braking from speed, especially when the surface is less than perfect.
Fourth, the car had a tendency to "float" a little, on undulating roads, which apparantly is down to the springs. Well, it still does it a little, but nowhere near as much.
I am told that my car would have tended to understeer with the settings before adjustment. I have never felt this was a problem as obviously the front diff would be compensating.
Previously, it had always felt less focused than the P1(which has had bumpsteer/alignment) from a steering point of view.It didn't react as well to steering inputs and I had always felt slightly detached from what was going on beneath me.It now feels very similar,but slightly softer. So much more satisfying and a joy to drive.
Quite easily the best modification I will ever make to the car.

Hi Russell,
Thanks very much for your comments. In that case, I will definitely try what you suggested before forking out for new tyres. I will do a search for Powerstation (don't know where it is) to try to find them, if you do read this could you please let me know where they are in case I don't find them otherwise.
Thanks very much. Steve.

Russell.
Thanks very much. Just re-read your post. The main issue I have with the 18s is the increased resistance to turning off the straight ahead. You mentioned that this was much improved after the visit to PS so hopefully this will be the answer. I'll let you know how I get on.
Best wishes, Steve.

The P-WRC1 (P1) wheel is available in two different offsets, ET53 for all cars except ones fitted with the STi Brembo brakes which need to be ET46 for this design to clear the calipers. Whilst this isn't the ideal offset, it does work OK on this car with PZero Nero tyres.
The P-FF7 wheel is ET51 and fits all 01MY on car (inc Wagon)
Regards
Mike

As we have spent a large amount of money testing various alternatives it would seem a little foolish to then give the information away for free
It would also be wrong to critque other tyre manufacturers tyres even though we have no exclusive contract with Pirelli.

hmmmmm, so does that mean there are tyres out there that perform better than the Pirelli you are sugesting? Everyone and his dog knows Pirelli make great gravel tyres, but their tarmac tyres are not up to the competition.
Personally i have found Pirelli road tyres to be poor in the wet, and average at best in the dry.
I am just trying to establish what reference point you are using in recomending these Pirelli's and whether you are biased, or contracted to only sell those.
When was the last time Prodrive recomended a non Pirelli tyre on its subaru range? what was that?
Thanks for answering the contracted question, shame you didnt the other, more important one.

Let's see
We aren't tied to Pirelli contractually in any way
We've tested various tyres
We fit Pirelli tyres on our cars
Draw your own conclusion (you seem to have anyway)!
I'm not saying that Pirelli tyres are necessarily the best for everybodies car, indeed some drivers may not like them at all, just that we haven't found anything else that
fits our criteria as well.
You will also notice that Subaru themselves have fitted the S202 in Japan with a Pirelli tyre (as they did with the 22B)
Your comments about WRC tyres is somewhat flawed as not many people seem to be winning with Bridgestone, Toyo or Goodyear tarmac tyres do they? The Pirelli tyres seemed to work quite well for Monte though. Lots of people recommend Michelin tyres for their Subaru as well I suppose
We are of course totally biased as we only use suppliers that give us unrivalled service, excellent backup and aftersales care as well as a good product at a reasonable price.

LOL
Thanks mike.
I dont put Pirelli on my own car as i think they are pants. I have driven rather a large number of Impreza's though, on track, road, gravel, snow, frozen lake everything from a 22B down to a Sport and then back up a bit to a 2.5RS, some with Pirelli tyres installed, some without. I havent changed my opinion yet.
Horses for courses i know.
Maybe you could educate me to Pirelli ways, because i just dont get it?

Going back to the question of steering and geometry checks.
Bearing in mind all the debate about warranties elsewhere on the site.
If you have your geometry set-up at anywhere other than a Subaru dealer, e.g. Powerstation, TSL etc will this affect your warranty?

Steve,
a) they won't know
b) Subaru dealers can't do it (to the level of accuracy that someone like Powerstation can
c) even if they did know, I doubt they could use it against you (it's akin to voiding your warranty if you get your tyres changed at Kwik Fit instead of a dealer)
