What's the ideal set up for track?

I'm looking forward to next year and plan on changing a few things, currently on std arb's (2002 bug sti)

Current set up is bc br coilovers which I'll probably keep, if I can keep them but improve elsewhere with different arb's then I'll be happy, track will be Knockhill (Archie can chip in if he likes) and I'm not fussed for road comfort as it will be predominately "track car".......

wrx 03 wagon. I have a 24mm perrin rear arb/stoutmounts, whiteline droplinks front and rear, strutbraces front and rear, whiteline ALK. You will need to upgrade the brakes for track. I have 8pot fronts but 6 pot are good and brembo's on rear. I did have BC's which to be fair were good on track but came a cropper in the wet when I had the rears set too hard. It has been added to over the years and I haven't driven anything else but it does go well. It's very planted compared with the standard wagon which used to roll all over the place.

Have you left the std arb up front?

Brakes are std Brembos but with uprated pads and braided lines and they're ridiculously awesome, on par with my Alcon brakes on the Evo albeit with ds2500 pads fitted, once i kit them out with xp's they'll be somewhat better than the bug brakes.

Yes never got around to replacing front arb, I might still look into it. Brakes sound good mate.

Wull Ive a bug sti that handles very well.I’ve done front and rear arbs and drop links and front bump steer kit. I run st coil overs made by kw. I have 6 pot ap fronts and standard rears.The setup at the geo I used was fast road/track.
Worked well at Prescott ��

24 front and 24 rear be good all round but I know the new age lads like a 27 front.
In my opinion for knockhill 24 front and rear. Being sponsored by whiteline as Wel I had the whole catalog I'd recommend going for the roll center correction kit to.

What size arb?

lol throw the BC's in the skip lol.
Agree 24 front and rear to start with, depending on dampers, tyres etc then maybe a 27 front but doubt you will need it. Just so happens I have an almost new front 24mm adjustable bar and drop links

Wull

What's settings can you get with it being adjustable? Softer? Harder? Both?

Adam K reckons 24 f&b, so sounds like a good place to start.

Two positions on the front and three on the back but your dampers will hold you back much more than roll bars will. With the right set up and the right driver the newage cars work well with a 27 mm front.

Interesting this, I thought the usual thing was to go bigger at the rear on Newage? Doesn't a massive front ARB make it understeer like a pig?

I'm currently running 22mm front and rear with the front set soft and rear set hard and I think it's a really nice setup but I only have the standard setup to compare against.

Wull

My mistake, Adam says 22f and 24b would be a good platform to start with with mak s sense, especially as I feel the bug has the tendency to understeer.

I agree Archie but like I put above the plan is to keep them for just now, maybe further down the line but if I can make improvements just now and keep them then I'll be happy. In an ideal world I'd go daft and buy awesome suspension (can't think of any that are for sale ) but the plan was never to do that.

I seen your updated post, do they actually fit straight on to the newage Impreza's?

So many factors. I would start by stiffening up the BCs on the rear and seeing what difference that makes. 10 click difference front to rear made a great difference to mine on a sprint track to bring the rear round.

Wull

Just checked the damping settings today......

Front is set 4 clicks from soft and the rear is 1 click from soft

I have Meister R coilovers on my blob wagon, with whiteline droplinks, an STI (20mm) rear ARB and poly bushes. I've left the front ARB and drop links alone for now. Also have front and rear strut braces. The biggest change was putting in the bigger rear ARB (standard wagon is 17mm) and bushes, pretty much eliminated the understeer. Rear camber bolts helped too, set at -1.2 rear and -1.5 front.

Stiffening the rear will reduce understeer, stiffening the front will reduce oversteer, stiffening both ends at the same time will reduce roll but not change the balance.

Wull

I wish I had checked the settings sooner, I could have had a little play to see what improvements I could have made and hopefully seen improvements.

If I keep the bc coilovers which I probably will then I'll change the settings and see how it goes, I was struggling with the front end running wide on a few corners, in particularly Scotsman and when getting on the power coming out of the hairpin.

Hmm. Wull, what ride height do you have? I'd start as high as you can, as the strut roll centre changes a lot with lowering. RCD kit is OK at the front but the rear suffers as much too. A Track car does need to be low though, so a front RCD kit, a bit of rake and play with both ends to get the car to roll level, rather than into a corner. ARBs are a compromise and if it's possible to get a nice setting without uprating, then I'd always go that route first.

Once it rolls flat, rolling is down to spring rate. An Anti Lift kit then cancels out all the anti lift/anti squat so pitching is also down to spring rates.

If you can get a good rake, front splitter for aero, an RCD to stop front roll centre heading towards Australia and let your damping be the final tune. I'd start with 15 turns as a base point for faster work. 8kg/6kg maybe for springs?

Best of luck, there's so much you can do to an Impreza!
