P1 FEK

iTrader: (1)

I have a year 2000 Impreza P1 and I'm looking to upgrade the front and rear anti roll bars and rear drop links. The car is already fitted with Apex coilovers and adjustable front top mounts and is used primarily for fast road use and occasional track use, maybe 5 or 6 times a year. I have looked through various websites and would like some information on which anti roll bars would be most suitable for my application?
I was thinking of Perrin 22mm front and Perrin 25mm rear, but wondered if this maybe to hard on the rear and I would be better of with the Perrin 22mm rear set to hard and the front set to soft? Or I was thinking of Whiteline 22mm front and Whiteline 24mm rear. The Perrin gear seems good value for the quality and front & rear Perrin anti roll bars come supplied with the stout aluminium mounts as standard, where as with the Whiteline equivalent the up rated mounts are extra.
I have contacted several well known tuners and asked for advice on the most suitable for my application but the information I’ve received back is conflicting and has left me just as confused.
“The 22mm rear ARB on full hard is roughly the equivalent of a 24mm ARB with the 24mm ARB on full hard being equivalent to 26mm.The ARB’s come with uprated bushes but not mounts. If your running the 24mm or 22mm rear ARB on full hard then the HD mounting kit is fairly important. On the Classic Impreza we would normally run the adjustable 22mm rear ARB with the standard front ARB. Only on the new shape Impreza’s do we always fit a front ARB as well. The steel links are much better than the standard links but not as strong as the Ally links.”
“22mm front and 24mm rear is the ideal setting the roll bars & rear d/links
can I suggest an anti lift kit which eliminates front end wash out (understeer) poly steering rack bushes & front d/links this is the best set up for your car
the mods can de done in stages but I would go for the rear-front arbs and d/links first”
Looking for advice or experience of this as I don't want to buy the wrong kit?

i'd upgrade the rear but leave the front standard.

personaly i'd go for the whitline 24mm rear and leave it at that (what i've got on mine)

also anit lift kit, and drop links all round and should handle very well indeed

IMHO and 5 years of experience:

Go for quote # 2. 22/24mm bars, ALK etc and rear camber bolts to get the geometry ideal.

What is the ideal geometry set up for a classic impreza.Do they vary from year to year?
Should I go with the settings in my Prodrive handbook?

Again, in my experience, there are better settings than the Prodrive ones, but much realy does depend on what you want to squeeeeze from the car.
If you add too much negative camber all round then the tyres will werar quickly on the inner edges, esp the fronts, but it will corner a lot better (on the track)

As ever, this is all a compromise.
Find a Subaru specialist who does actually know what they (he) is doing, and the car will be great.
