The factual bit:

As many of you know, I spent many hours down at Star Performance two days ago…12 hours in fact (08:45-20:45) having a play, testing a few things, having a load of work done, trying out a few things etc.

Firstly, thanks to Jim & Brian…12 hours and two meals later we were all knackered!
Credit where it’s due…anyone looking for decent service, advice and standard of work could do a lot worse than giving them a shout.

Secondly, none of this was free…labour rates, wheel alignment rates, dyno time, replacement parts…all paid for out of my pocket...I have the invoice for over £900 to prove it!!

Thirdly, these are our (mine, Jim’s and Brian’s) observations based upon our findings. All testing carried out with conditions kept as close to previous conditions as possible etc…some will disagree violently, some will agree…that’s your prerogative.



Finally...the bit that brings all the other suspension bits together...the set up!

I find the S3 understeers badly wet or dry...there's too much roll and not enough grip.

Fitting uprated dampers will have helped the appalling standard (worn) damping, and adding the ARBs will have helped prevent roll whilst bringing the back into play a bit...but there's still a lack of front end grip (that phrase will please AL B!)

As discussed previously some time ago, the S3s have adjustable front ball joints which allow you to pull them outward and add negative camber. Fitting lwered springs also adds negative camber BTW!

Anyway, previous to this playing about session I had pulled my balljoints out as far as they'll go and gained -.15 degrees negative one side and only -1.0 degrees the other...better but not ideal as not equal...and I didn't want to reduce one side down to -1.0.

So, since the subframe had been off we had the opportunity to move it about a bit...I now have -1.3 degrees negative camber each side on the front.


On the rear, when you lowrr an S2 you get too much negative camber...the use of the Forge Motorsport Adjustable Upper Arms mean you can adjust this back to standard, or whatever you want. we fitted the Forge arms and set the rear camber back to -1.0 degrees per side (standard)


For rear toe - which is not adjustable - it sitting at toe out (can't remember the figures and I left the set up sheet down at Star! Doh!)
But I'm happy with toe out at the rear...it aids turn in.


The front toe should be set to slightly toe in (4 minutes toe in)...which is great for everyday driving...but a bit compromised for the 'press on' stuff...we set mine to slightly toe out...it tends to add a bit of front end bite. I think we used 5 minutes toe out per side.


How does it drive?
****** fantastically!!

There is more grip at the front than I thought possible..it doesn't lean/roll on turn in like it used to...which takes some getting used to as it feels like it's going to start understeering...but it doesn't.

Keep your foot in and you can feel the rear come into play. You turn in and the rear just follows - regardless of speed...it just seems to find a point at which the torque goes to the rear, loads the suspension up and catapults you out of the turn.
No understeer, no oversteer, just pin sharp, precise turn in and a perfect line through the bend. I honestly never thought an S3 could feel this good to drive.

It's totally predictable, unbelievably grippy and the feeling of confidence it provides for the driver I've never felt in this car before.

I'm absolutely gobsmacked at how goos the chassis feels now...there's even a bit of feedback through the steering now!

I'm sure Grant (Imola S3) will be able to testify as to the way the car corners now...it's transformed!


This car may actually topple the Integra Type-R off top spot as the best drivers car I've owned... only time will tell.

I'm a very happy man now...
And since I've worn my keyboard out over the last few days, I'ff off to drive the damn thing...what's the best bait for Subarus nowadays anyway?

 
I can confirm that Glen's car goes round corners like it's on rails! I've never been in a car that handles as well as Glen's S3.

The speed that this man took corners last night almost made me soil myself! I will honestly admit... last night, Glen had me **** scared!

Fighting talk from you? It must be good!

Must add, most excellent reports. /ubbthreads/images/graemlins/groovy.gif I was at Star on Saturday last week (new DV) and it was mentioned you were getting assorted work done, but was all hush hush /ubbthreads/images/graemlins/angel.gif

Trying to decide if/what to get done. Would need to be good value and not wreck the ride and/or tyres any more than normal. Don't really want it lowered, so considering dampers and maybe just the rear bar at 16mm. Will have a chat at the next meet /ubbthreads/images/graemlins/beerchug.gif
 
With the geometry then yes this does cause the tyres to wear more quickly. If you push hard in the corners then they will wear fairly evenly, otherwise they will wear on the inside edges quicker. But it is so worth it.
 
Ok had my 8l S3 on the Beissbarth today. Still running stock shocks/springs but I've recently fitted new front top mounts & powerflex front wishbone bushes so thought I'd line er up. (the PF bushes do seem a bit to hard & seem to make the front feel a bit rough so I may go back to stock)

Front now set to -1.25 degrees camber a side, -0.04 toe out a side, +7.40 degrees castor a side. Rear set to +0.08 degrees toe in & the camber -1.56 left/-1.38 right. Its a bit much negitive camber @ the rear for standard ride height but i don't have adjustable arms & the tyres wear ok so not bothered at the moment.

The tyres I'm running are 235/40 18 @ 32psi front & 225/40 18 @ 36psi rear.
In the dry the car grips & handles good but in the wet the wider tyres on the front grip more & I need to press a bit harder to produce front wheel slip & bring the rwd in to play, when the rear does take drive the thine/higher pressure tyres allow a bit of slide.

I'm now wanting to try some skiny 15" all round in the wet for some 4 wheel drift. lol


Ewan.
 
Never get them over the brakes.

Ooooh minty,I saw Biggieds post and thought who is going to be the first to tell him that...bearing in mind he sounds like he knows a lot anyway. :)
 
Ok I'll mabey try a set of 16'' with 205 tyres. I take it 15s have been tried before then?


Ewan
 
get four spare tyres and try them...should be fun.
cannot think of anyone trying 15's or 16's
 
16's minimum over standard brakes, and you will still need the correct offset for the wheel spokes to clear the side of the calipers. A set of Mk4 Golf V6 4Motion 7 spoke 16's would be ideal, as the car has the same brakes, and I've tried them. car sits a lot lower though, and the wheel arches look stupid with the smaller tyres.
 
what would i need to go with some ap coilovers will they do by the self or can i get owt to make handleing any better tar

Took me a while to work out what this actually was in english but I am assuming you are asking if you need anything else to go with your AP coil overs to improve handling?

Uprated ARB's would be the next step and you have asked that question in Pt8 Anti Roll bars thread you posted in so have a look there :)

Holy thread revival time :)

I'm booked in at a race specialist tomorrow for a complete 4 wheel alignment and wondering what the best setup would be on the following:

Standard shocks/dampers
TT springs (Rumoured)
S3dave rear tie bars - lower/bottom
New track rods
New front ball joints

Complete SuperPro polybush kit with alignment correction. This kit includes eccentric castor correction bushes for the front lower arms and eccentric camber correction bushes which I have fitted to the upper arms only due to the s3dave tie bars on the bottom.

Car will mainly be used for daily road use with occasional spirited driving and possibly some occasional track use in the future.

Any help/advice is much appreciated but I will say that new springs/dampers aren't an option atm due to lack of funds.

Many thanks, Shaun.
 
Where you going for it doing shaun? Need mine doing.
 
Doesn't having parellel toe help with tyre wear with added camber?

I'm running around 2.5 at the front currently and tyres are wearing pretty evenly.
 
can i add that rear toe on s3 is adjustable, as i watched the 4 wheel alignment guys adjust mine - admittedly it was with a large hammer because it ws very tight/almost seized, but it is adjustable.

Sorry for the olllddddd quote, but since this thread has just been revived I thought I'd make my move :p

In the other thread (pt8) you said that don't update ARBs on standard Springs and dampers (albeit this was three years ago). If I got upgraded coilovers (that have no damper control) would there be any point upgrading the ARBs? I'm thinking AP coilovers at this stage
 
Well... I have just fitted R32 arm's front and rear and the car feels so much more planted in the corners... Take from that want you will but I am glad I did mine... I do have B8's and apex springs of course

<tuffty/>

Thank you for that. Would you recommend damper & height adjustable coilovers over just height adjustable coilovers?

I don't want to fork out for the ARB's to find it ruins the handling due to my suspension not being suitable, since AP coilovers aren't damper adjustable..

I have no real experience of coil overs on a road car other than when I had Spax RSX on my A4 and they quite hard all things considered despite being adjustable and the KW's that Bill has on his Mk5 chassis Leon Cupra which are pretty impressive although part of the feel is from the improvements of the Mk5 chassis over the Mk4

I like my Bilstien B8/Apex -30mm combo especially with the R32 ARB's but handling and ride is too subjective to 'recommend' anything realistically

I think it's ok to upgrade your ARBs on standard suspension if your shocks are in good condition, but not recommended, I certainly don't see the point of upgrading on standard stuff, but that's just me. If you are running uprated shocks, then there is no problem with doing the ARB upgrade, it really depends on what you want from your car? If you are slamming the car to it's lowest setting on a set of coilovers, then save your money.

I will barely be lowering the car, if I do at all. If something gives me a better ride (ie less body roll without being too much harsher) id be happy. I know coilovers can be quite hard but I'm happy for that.

I think I'll give the ARBs a miss for now, see how it handles with the coilovers and then go from there
