Craig, how's about asking Mr Comas what his tarmac settings are?
Craig, how's about asking Mr Comas what his tarmac settings are?
I'm sure Mr Comas has better things to worry about than me calling him up to ask what his suspension settings are!!Originally Posted by strat24v
As we have covered earlier in the thread a car which is set up for competition or drifting will often have more aggressive settings such as toe out which help to promote turn in (track car/rally car/drift car) &/or instability (rally car/drift car) in the interests of ultimate times or visual flamboyance. A road based Strato's replica should be set up for performance & handling but with a concession for compliance & safety, ie stability under braking & predictability when cornering.

Can I just chip in on this one,
What Craig is saying on castor is what I have found during my rebuild.
When the front suspension was put back together without springs, it gave me an chance to check the bump steer through the full stroke of the damper, I checked the bump steer and as you start putting on more caster the toe in to toe out change was huge.
At the moment I have reduced the caster and raised the rack on shims.

Let me rephrase. The car is really a delight to drive turns in well powers out of corners with no drama even in bumping conditions. The twitchiness I am refering to is the almost lack of self centering. I am not going to dipute others experiences but I dont like the tone of this conversation so this will be my last post on this matter. And no the TBs are not going anywhere.....
I'd say you have issues with steering stiction.

The 215 x 15 Michelin TB15 is the cream of the crop for the front end of a Stratos rep.
The new P7 Corsa might be on a par, but I doubt it's any better.
A Hawk needs to have the correct offset on the front wheels.
That, and any 'give' in the front tie bar (tension strut) bushes can make a Hawk dart about on the road.
So much so that it will be an awful thing to drive.
Yes, maybe, but only if you cannot live without 15" wheels. There is a trade off between appearance and practical handling.
That's why I hate Ferrari Dinos or 308s fitted with 16" rims and lower profile tyres.
It makes (handling) sense to ditch the 70 series rubber, but if you wanted something more modern?....
This, for example, will be an arrestable offence when I come to power:

Reducing Caster will reduce self centering action further - Irun 5.5 positive on all my cars.
Bump steer has little to actually do with going over bumps. - The sensation is a lack of front end stability when the suspension is compressing with undulations as the suspension is loading and unloading in normal driving conditions. (apologies if teaching granny)
Everything done to your car by the "experts" you took it to for setting up is contrary to the established norms and experience of setting up any mid engine car, or any car for that matter not just a Stratos. The settings you have advised us of are a concern to anyone who has driven a mid engine quickly.
I would be very concerned about the lack of rear toe if corning in the wet especially coupled with the front toe out and what sounds like uncorrected bump steer.
Everything is comparative and a TB15 could well be termed "sticky" when stood against a Yokohama A539 - but compared to an Avon ZZR soft they would not be.
The "Tone" you refer to (looks like a bit of lightheartedness to me but maybe I am a bit more thick skinned) is because you are apparently choosing ignore a great deal of experience and people are genuinely concerned for yours and others safety driving with those settings. I certainly would not fancy my chances of making it round a bend if going quickly and finding water on the surface half way round - then again what's quick to one is downright dangerous to another and you may not drive the car in a manner that the settings you have would be an issue.
