sprint camber

#1 Post by sm519193 »

so having read a few of the posts on camber I'm still not sure if I understand it or that my sprint is correct.

I have just changed the rack, and thought it best that I get the tracking done professionally, as it happens I wasn't to far out with my own efforts.
doing this brought up the questions on camber.

The manual states 3/4° Positive ±1° on the forums it seems negative is where people want to be! hence the confusion
looking at my results is mine good or bad?

I'd say leave it where it is, a tad of neggy camber never did anthing any harm! If the suspension has been lowered a bit, whether from tired springs or deliberate action, you will automatically get more neggy camber from the unequal wishbone design. But there's not enough there to be needing any action as regards re-shimming the wishbones, even one shim added each side would probably take out of tolerance the +ve way, which would be worse!

Hi Steve, That is an interesting question. Good one !
I remember the Hillman Imp being introduced in 1968 (?) and that was distinctive for it's positive camber, though I think they modified that later. I have always checked my Dolomites to have slightly negative camber and you are quite right in that the manual actually specifies slightly positive camber. :shock:
Smack wrist !
I agree with Steve that it is a lot of trouble to go to to change it ... and then you need to redo the tracking.

I found a reference to camber angles on Wikipedia; it makes for interesting reading.

I wonder if this is the reason that wheelchairs used in sport have large amounts of negative camber?

The Imp was introduced in late 63 for the 64 model year, i've owned several! Performance Imp specialists produced bespoke lower wishbones (and/or adjustable inner wishbone mounts) in period that let you use a good ration of neggy camber. These parts are much sought after by Imp owners today.

The Dolomite factory setting is indeed +ve 0.75 degrees, but it's + or - 1 degree, so you could have a touch of neggy and still be within limits. The Carledo is lowered 2.5" from standard (Toledo) ride height which gives (without re-shimming) just about 5 degrees of negative camber each side (4.60 and 5.33 if you want to be picky) I've suffered no ill effects from this, the pocket rocket corners as if on rails and doesn't wear the tyres unevenly.

Sporting wheelchairs have massive neggy to help avoid overturning with excessive tilt, the wider track it gives, gives a bigger base to contain the CG within.

The main reason sporting wheelchairs have such negative camber is it allows hand to wheel contact for a greater extent of the circumference which assists with both outright speed and agility/control when pivoting

Hi Steve, Yes those numbers look fine, very similar to mine and you can sleep easily at night if you leave it like that.
It is always good to check though.
Cheers for now,
Tony.
