CIH

a little tail-high isn't it (before and after) ?

oh I forget it should be pre-93 so I wouldn't have to merf around with Cats. Meh, Rover....Jap styling but without the build quality.

Just read through this thread start to finish. I'd be fascinated to see how WIM's kit compaires to the fast fit stuff I use every day. Even the air/com machine looks twice as big.

Don't think I'll get a MX5 for ~£1k. How about an MR2 (mk1 or cheap Mk2 n/a) ? Or do they deserve their rep as a bit terrifying when pushed ?

With the changes in castor the SR moves on the longitudinal axis travel too ? I never would have guessed so much movement with a simple steering wheel input but it seeems obvious now.

I'm reduced to using Forza, and it's Replay Telemetry, while I'm at home but with steering on full lock, camber was diametricaly opposed. Is that true of SAI and toot ? ie, the figures obseved with the steering in one direction should be consistant with the other direction ("mirrored"). Unless you were looking at a Galaxy, that is. Is this a similar situation to Included Angle in that you're looking not for specific figures but for consistency acros the axle ?

I think I can see where this is going but there's no point I'd like to clarify. Am I correct in thinking that hard cornering, and the associated shifting of the vehicle's weight, will impact on camber ? Ie; as the inner wheel moves to an unloaded state, as the weight of the car shifts against the direction of the turn, the inner wheel will move toward positive camber and the outer wheel, under load, shifts toward negative camber ? I assume SAI won't change significally, save for any give in the rubber components ? So, Scrub Radius (SR) is the actual point of contact between vehicle and tarmac. This is determined where Camber and SAI angles meet. When the wheels are at the straight ahead this should be at the centre of the tyre tread. The SR will migrate across the tread during cornering, due to (or in part to) dynamic changes in camber. Am I correct so far ?

Has anyone any experience with any of the numerous MX5 Owners Clubs ?

On the DSP600 you have to do a castor swing (20 degrees) this swing acquires the secondary angles but it's not displayed on the main screen unless prompted. Ackerman and TOOT are the same thing just different terminology.... what understanding do you have of either? I can't recall any options to view toot using the usual tabs ? As for TOOT/Ackerman, I only understand so much as I understand it's a similar reason a car requires a diff. That is, the outer wheels travel a larger distance, and a different arc, when negotiating a given corner.

If anone reads Pratical Performance Car they'll know there's a regular contributor who runs a rolling road. He kacked his pants driving a similar Maserarti. And he was running it up to speed on the rollers too!

DSP600

No, it was an end-of-day rush job so I was pushed for time. Toe and Camber were symmetrical across the front axle so I was reasonably content to leave it as was. Would you have stayed within BMW tolerance or gone further to a neutral angle btw?

Off untill Tuesday now so it'll take a while before I do another Hunter. I've noticed the primary angles give no indication of SAI. Haven't looked for a while but is there a Seconday procedure specifically for SAI (such as there is for TOOT etc) ? I'm going to try and "sneak in" some secondary measurements in the future as I'd never even heard of them prior to WIM. edit: Could you get into more detail in defining Ackerman please ? Especially how it differs from TOOT ?

No silly tools. And no mistakes this time. Well, other than mis-typing the mileage anyway... edit: oh, if you're wondering why left rear was so bad, it's had a new spring.

No , it wasn't as severe as that. It was confined to the tread. Took a picture with the camera phone but it's very poor. I know it's hard to say without actually seeing it. And yes, he knows what I'm up to. Anyway, back on topic ?

do you not find non-assisted steering to be really slow though ? I can remember reading Ferrari etc resisted PAS untill they concluded it was needed to allow fast enough steering response to driver input.

I understand Westfields are notorious bump-steer'ers due to poor location of the steering-rack. Incidentally, remember our hyperthetical MX5 scenario ? Had that today. Facelift Porsche Caynne (Jeep affair thing). To look at the tyres I'm immediatly thinking Camber. Smooth wear, localised on outer edge on all 4 tyres to varying degrees. Slapped it on the rig and all primary angles were near enough spot-on, save for Steer Ahead which was wandering -/+ 2 minutes. Was at loss but given it was still under warranty I advised get it back to Porsche with a copy of our report and one of the tyres in the boot. Maybe a bad bush somewhere ? Y'know the more I look into this the more I'm getting frustrated at KF. I'm just skimming the surface and, as my Hunters are taking longer as I respect ride-height pre-checks, pre-loading etc I'm under more pressure. And I'm only measuring primary angles at the moment too. That rig is wasted on KF.

clutchless paddle shift, per chance ? is that a Clio V6 hiding behind the E36 ?

Pretty trick for a warmed over shopping trolly....

Just one quick point to Q4. If aftermarket TREs were fitted would that require bespoke toe settings ? Or would factory suggested settings still apply ? Otherwise I'm good. I actually quite enjoyng this

Frm pictures and my whiteline catalogue it looks like Struts with parallel links and ARB: Same as the ZX Sunnys I've been looking for.

Trying to decide what to get for my next car. So far I've been looking at 80s Nissan ZX SIlvia, Bluebird and various Sunnys but it's taking ages finding one suitable. Also, I've fancied turning it into a budget track toy and, as i'm studying Geo it'd be handy to have something to play with. I want something fairly cheap (~£1000), upto 2.0 (non-turbo) and something that lends itself to be modified. Mods would be interior strippage, brakes, wheels and most of all suspension- ideally coilovers for full adjustment potential. I want something Jap, 80s/early 90s and either FWD or RWD as I'm not especially fussy. Now, I know what you're thinking. MX-5 right ? Should be perfect but, despite myself, I just can't like them. I don't know why I just don't! So how about an 80s Corolla GT ? I like it. Slammed om Jap rims and mild mods. Incidentally, mailed the guy and TLC means missing some interior odds 'n' sods, N/S/F rusty wing and a bad respray. Wing should be an easy fix (assuming a replacement can be found) and the rest isn't a big deal. Would prefer Nissan as I like 'em but I'm getting bored not having a car.

No doubt the tyre bods, if you were to go back, will try and sell you a tracking. Just my sense of humour :glare:

I like nice, fairly straight forward twinks like the 4AGE as found in AE86 & Mk1 MrTwos. Or Nissan's 2.0 SR20. Infact, a 200SX CA18DET (1.8T) but Supercharged instead would be my favourite engine (at a realistic level).

1) Okay, got that. That's straight forward (uh, no pun intended!). 2) So an asymmetrical SAI indicates a bend somewhere within the chassis as a whole. The IA can be used to determine wether it's within the sprung or unsprung areas. Ineffect, narrow down the search. I assume simply correcting camber would be illadviseable ?
