Corner weights of a 1303

[Steve C]

Hi

Just found some software to do corner weights, I used weights that Chris posted.

I imagine getting the car onto a scale would upset the suspension.

Bah. A "trucker's scale" used for individual axles/tires could be used with small sheets of plywood glued together to be at the same height as the scale. Jack up the car, put the scale under one tire and the wood under the other three. Rotate as needed to weigh each corner.

Instead of purchasing such a scale, simply contact a local shipping/freight company and see if they have such a thing. If not then your local Co-Op should, since they have to have some way to weigh their grain trucks.

If MacGyver could build a nuclear powered submarine out of a waterbong, a paperclip and a ball point pen, then this should be easy.

Hi AggieDave

Your idea would work in a fashion.

What I was getting at by upsetting the suspension is, as we all know the suspension will slightly tuck under during lifting and the only way to settle it back to the correct ride height is to move the car, this tuck would raise the suspension throwing out fine corner weight measurements.

Get one scales and 3 dummy scales. Drive the car onto the 4 items, measure. Drive off, swap the scales around, drive on. K.I.S.S

your car and scales need to be on a perfectly( or near to it) level surface. otherwise you will get incorect readings, theres no way around it period.
You can use adjustments for ride height to shift weight and you can also simply use dead weight (such as lead) to do the same. its all a balancing act.

with adjustable 944 spring plates you can do a lot.
the goal is to get your cross weights near 50%

Sure but I was pretty much assuming that someone on these forums asking this sort of question wasn't worried about that. Basically that if someone was worried about the cornering weight to that degree, that they'd have a source for scales in pit row at the track. Even then, after the crew chief sets up a car "perfectly" for which ever type of race they're racing that weekend, after some practice laps the driver always comes back and wants it changed for his/her liking.

So all the measuring, weighing, knowledge and skill about suspension on the mechanics side is tossed out by the worlds finest judge...the driver's butt.

There are cheaper corner weight gauges available which use a lever assembly that hooks under the top of the wheel rim. push to lever down to lift the car and then the gauge shows the weight.

but I decided I couldn't afford it....

Much cheaper to just go somewhere (like http://www.raceshack.co.uk) and borrow their corner weight scales.

Hi

Andy those units look like the way to go.

Aggiedave, I agree about the drivers butt, corner weighting is one part of car set-up that is scientific, if your turning left and rigfht even weighting needs to be achieved, if your only turning left hand corners or right hand corners, corner weights can be set-up to suit the drivers butt and track.

One set of bathroom scales and three garden pavers...?
