Just fitted a load of suspension goodies and had the rear lowered to match front and its time for tracking.Question is do i go the normal 1 deg of toe in or get it set parallel??.....cars mainly daily/fast road car with occasional track session,im going to the ring in 3 weeks so want the best set up for that really.Is the increased turn in noticable with the parallel set up and how much straight line stability would i loose.

My set up is bilstein B8/B6,eibach pro,roller bearing wishbone bushes,hybrid ARB,solid rear mounts.

Why not -1 ?

Thats according to Micheldever Tyres They had no idea what to set my track schlagg to when I turned up ages ago ?

-1 sounds a good shout ?

I pretty much have the exact same suspension setup and was about to post a similiar thread, so I hope I'm not hijacking.

What would be the best alignment for a car focused on handling/mid corner grip rather than straight line stability?

As I understand it, the solid wishbone bushes will play a part in the final alignment decision as they will not tend to toe-in under load like standard bushes.

Cheers

1deg toe out, extra castor and touch more camber....either way will cost a hefty amount.

I set mine to parallel and found it was a bit unstable at speed/when accelerating although that's probably due to the power I am running, I then tried with a bit of toe-in and found it much better, all I did was turn the track rod one full revolution on both sides although fook knows how much toe-in that is, worked for me though,

You could set yours to parallel, try it out and then if its no good adjust for a little toe-in like I have Smile

I would go with parallel, having recently gone through 1deg toe in, 1deg toe out and then finally parallel (all within 2 days just for back to back testing, luckily its all free!). Parallel improves turn in and doesnt harm stability much at all, its the best compromise!

Thread revival here but I went to do the tracking on my 6 last week and Autodata lists it as 2 degrees Toe in.... +or - 1 degree. So I thought 2 is somewhat high and set it at 1in and now really don't like the feel of the car to be honest.

I have 30mm springs b8's and rear lowered to match but stripped so probs 40mm rear to sit level. Also have upper an lower strut braces and a brand new rear beam with hybrid ARB.

Thinking of setting it to parallel tomorrow lunch break to see if I'm happier with it. Has anyone else tried this? What do people with track cars run as the car is purely a toy for hacking through twisties not a daily.

Just curious... what did you not like about the feel of the car and what was the setting before it was adjusted?

As above usual rules are that some toe out will improve turn in response while toe in will help with stability. I don't have a full on race spec car but usually run not more than 1 deg toe out (~1mm to 5mm at rim) and it's great. Whenever I've made changes to toe I usually also changed something else on the suspension so I don't have definite comparisons.

I usually set mine to as close as I can get to parallel, I think 205's are specified to much the same.

edit, looking at autodata, they are the same spec up front unsurprisingly, 1-3mm toe on a 15" rim, or 0.10 to 0.30 degrees.

I'm running 17" rims to fit the 330mm brakes under.

It was out before but was set to nearer 1 degree the wrong way. Turn in actually doesn't feel as nice and if hacking round a roundabout I have less feedback and it feels like less grip as well. Think I'll try going close to parallel and see how it feels. Have a super tracker lazer setup at work so just costs me time.

I think some toe out in effect gives you more ackerman geometry hence why it would feel like more grip and feedback since there would be less rolling resistance, for low to mid speed steady state cornering at least- e.g. round about- Too much toe though and you will get terrible tyre scrub and a numb sort of feeling during initial turn in. (theoretical- this could be total nonesense).
