Corner weights of a 1303

[andy1303]

Anyone have any idea how heavy each corner of a stock 1303 is? I'm trying to work out spring rates and don't have a gauge....

I had my car weighed when I got my T4 engine tuned up a couple of years ago. Its a 1973 1303. With me sat in it it weighed 939kg, and the following at each wheel:

Front left 200kg
Front Right 213kg
Rear left 246kg
Rear right 279kg

Excellent, thanks for that. Surprising isn't it really. That's not as much difference as you'd expect front to rear. Will we see your car on track this year?

[Chris Percival]

Yeah, it is. I have the battery in the front wheel well which helps. On average its a 44/56 split, front and rear, thats supercar territory..

Hopefully on the road, but probably not the track this year, maybe next..

Hi Chris

Is your car adjustable in the corner weights? Having the corner weights correct can really make difference to a cars behaviour.

I want to have my corner weights correct in my next car, Im on the lookout for a cheap way to do this. I've thought about making a hydraulic apparatus that could lift each wheel, I could then read the hydraulic pressure needed to lift the car at each corner. It wouldn't give me kilograms per corner like you have, but I could compare oranges to oranges, but the kilograms per corner could be worked out if I knew total weight of the car.

As I have adjustable struts, the wheel pressures could be modified by adjusting the strut height I expect.

What about using heavy duty scales, and just weigh one wheel at a time, adjusting them until they're even?
