Thx guys, are these applicable to newage models too? Mine is 06 spec c Ra

 

^ This is a good standard-ish fast road set-up, but you'll want something a bit more aggressive with your AST competion kit and 255 tyres Ilya. i.e. more Camber, more Castor and less rear toe-in. Makes no difference whether for Classic or Newage, the principals are the same. Only thing that makes a difference is what type of diffs you have and what you're planning to do with the car.

Just noticed you have '06 Spec-C. The settings i suggested will be perfect for fast-road/trackday use, the more Castor you can get the better

 

I agree, the Powerstation settings posted above were a little tame

Here's a setting I was using on my 370bhp JDM new age. This car had quite a few suspension goodies fitted (lowered Eibach coilovers and lots of Whitline) and drove devastatingly well.

I prefer a bit of toe-in (Prodrive recommends 0.15' each wheel for their P1) as while this will make for a little less sharp turn-in, mid-corner grip as well as overall grip will be higher

 

how much does this cost and wheres best near colchester ??

 

I have a 2006 Spec C (T20) with 360bhp with Powerstation's AST setup.

The insides of the tyres seem to be wearing faster. I had this too on my 2001 modded WRX with Prodrive settings. Is wear on the inside tyre walls to be expected with all of the more aggressive settings?

 

How much of the inside wall are you seeing wear on?

 

Maybe a couple of inches all the way round.

 

15-16' toe-in front & rear, where did you get those settings from?
That must have tramlined like a b!tch !


Elite Direct in Rainham, around £100. But get yourself a set of camber bolts and an ALK or Top-mounts (or ideally both) fitted first .


Yes, with anything over +1 degree of camber combined with toe-in you will naturally get uneven tread-wear on your tyres, but you shouldn't have wear on the inside walls unless your tyres are rubbing . Could try fitting some 2-3mm wheel shims if this is the case to stop them rubbing .

 

Yes, 15' toe-in

That's from the horses mouth - Prodrive's Peter Cambridge

 

I found major benefits by increasing CASTOR as much as possible, which gave me dynamic CAMBER when really needed.... when you turn-in and through the turn. Extremely good for road use imo.

I use the Whiteline adjustable top mounts and ALK (see my Project Thread for details), which have given me just under 6degs of CASTOR. It's rock solid in a straight line, no adverse tyre wear (a little over -1deg CAMBER fr and rr), great initial turn-in and mid-corner grip.

 

this is what my p1s got on it

front whiteline anti roll bar
front whiteline drop links
whiteline anti lift kit
rear whiteline anti roll bar
rear whiteline drop links
alloy wish bones
fully polly bushed
sti front strut brace
cusco h brace
sti pink supention , (ajustible soft to hard only)

Before making any decisions get a ride in a car that has the suspension you are thinking of fitting.
Suspension is something very subjective and what works for one may not for another.
If a car is mostly driven on real roads (rather than racetracks) you need a suspension that damps and absorbs.
Harder is not always better as a lot of people think.
Just my 2p after having driven/been a passenger of a few cars with coilovers.
The original shocks with a set of Prodrive/Eibach/Sti lowerting springs work really well for a road/occasional track car.

 

Very good advice. I would second the late V5/6 red struts & P1 Prodrive red springs as an excellent road combo

 

Almost 6° caster is impressive. I'm presuming that amount has been achievable as a combination of being a new age car, top mounts as well as the ALK

A castor kit as opposed to a ALK might achieve even more...?

 

You'd certainly have lots of grip with that much toe-in, but you'd soon scrub your tyres out for sure, and it would be very difficult to un-hook the rear in slower/sharper corners (it's good to have a bit of controllable oversteer in slow/sharp corners IMO, all about acheiving the right balance )

 

+6degs Castor would be very impressive for an Impreza road-car. Not heard of anyone getting more than +5degs on an Impreza before .

Top-mounts + ALK can add up to around 2degs, so does the JDM Hawkeye have +4degs Castor as standard?

 

It does sound an awful lot. My Blob JDM had a shade under 4° as std...

 

Again, this figure did look excessive to me when I read it (this month's Total Impreza). I like ~0°8' each side, but that's me

There again, I went along to a local Hunter alignment centre recently who had in their database P1 settings. It stated a tolerance of 0.01 to 0°15'
