CIH

Couple of disasters and a painting fubar meant I've had to scrap the Berkut and Foxbat so the CIH airfoce is looking a bit depleted. Still, it's all pratice and I've more kits (victims ?!) coming.

1) Toe front and rear only. And the N/S/R is damaged/worn as it makes very little difference either on or off cam. So not much then. Well I did say I wanted to explore "bilding in" adjustment via aftermarket parts! Probably be a while before I have the money to do so.

So does the car see dynamic camber gains in the same way as negative camber ? I'll have to get it back on the hunter and see how it reacts to pitch, yaw etc. Anyway, in the meantime and keeping it hyperthetical shall we explore what you had inmind ? 1) Stock for now 2) Fast road, track possible but unlikely. Will be doing the Jap shows. 3) (Will do) 4) Neutral to mild progressive oversteer.

Doesn't have to be an S12 specifically I was just curious about positive camber generally. Only other car I can think of with posi. camber were obscure early eighties Mitsi Colt Galants.....

The suspension articulation, the roll centre and the geometric gains command a deep static geometric position..... Well that's all fine until the coil's sag!.... Now the roll centre's gone so the car corners like a boat, plus the geometric gains are to pot hence the understeer and the tyre wear. The Omega has a poor dynamic index for all the reasons above... Areas like SR, SAI, weight transfer explores the fact the Omega has a desperate geometric compensation so that the tyres saturation limits are expanded.... But not without consequence. Odd plod use them/ued them don't you think ? Can we explore how positive camber could be desireable in my Silvia ? Seems contradictory to everything I've seen.

I hate Autos which don't "creep". Especially in something potent.

I like my format :nowink:

Reminds me of a Retro Cars featured Lotus S1 Espirit running an Audi V8 from a couple of years ago.

Bet it's tyres mate ...... "Off topic" very slightly, don't you think that print format is hard to read? Can an impact generate a phnumatic pull ? I don't mind the format but I'll admit when people type in their results (such as on a forum) I can't make head nor tail of it lolz No vibration through the steering wheel but I can check when I rotate them. Hope it is tyres or wheel as I don't want to start replacing parts when I plan on binning them infavour of adjustable stuff.

No. I was convinced it must be the alignment as it didn't do it prior to my "off" but the figures don't back that up ?

I think the nervous (dead spot ?) was probably the Toe. It feels more "solid" now but the pull is more pronounced. Pull is to the left. Camber is actually the opposite of what I was expecting, given the pull.

Yeah but the pull feels stronger, though the nervous steering has been banished.

The reason i say that was because you had no warning on the dash.... normally this means only one side had worn down without the sensor wire. I doubt Festa Turbos had wear sensors. Still, 18k isn't much at all for a set of discs.

Does that really say up to 1d positive camber OEM ??

SAI is only a couple of minutes beyond OEM so I personally wouldn't worry about that. Camber isn't too clever but IIRC isn't adjustable from the factory ? It probably moved when they adjusted Toe to spec. -3 degrees Rear camber is much too deep but again I'd be surprised if it's adjustable. Tony, do I read correctly the near-enough-even IA indicates an unsprung bend on the Near Side ? Haven't checked my notes for a while

So what is it about the Omega that dicatates such deep OEM camber ? Is it the combination of soft suspension, indifferent chassis and the fact it's such a heavy old tank ?

roll centre ?

In what sense.... are we talking aerodynamics? No. I've always thought high camber angles had certain inherent problems such as instability under braking ? Or is that incorrect ?

y'know the electric handbrake on Renaults has an ecu and needs the 100k gear to windback the actuator before you manually windback the piston. Can you imagine trying to fix a dodgy handbrake on such a car in 10/15yrs time ?

They're not overly yellow. Probably just the picture. Actually, thast reminds me. How about some oh-so-eighties yellow spotties ?!

Apparantly some VAG cars require the ECU be told Geometry is to be altered. They have a dash warning light for it, though I'm dubious as to how it would work without misinforming the customer.

Our service dudes recently got the new "plug in and play" tech kit and there's a scetion on Geometry. Some really interesting stuff. For example, on newer Renaults, chaning wheel sizes requires the ECU be set into a kind of learning mode so it can adapt and ensure ABS etc works as intended.

Glued and bolted, hence the little bits 'o red tape to cover the holes! Friend of a friend does bodywork so I'll get it properly finished in the new year. It really was knackered. They always are. Flapping about in the wind and what not. edit: do we like the new Avatar ? edit again: the situation with the pull may actually be helpful, assuming it can be rectified. I find it quite tricky to "feel" a pull on customers cars but with the S12 I now have a definite case of a genuine pull being introduced and can take the time to pour over the figures to see what's what.

Gave it a wash today and got sick of that damn boot spoiler so it had to come off

All 3 are in primer now. They don't look much different save the Berkut which is in a fetching shade of, uh, matt grey....?
