CORNER WEIGHTS

Anyone happen to know the corner weights for a non-reversing T1 (ideally, T2/3 would give me an indication)?

I've looked and not found, but wanted to check the ballpark figures before starting to fiddle with the front sus.

Thanks!

Squeaker is 360Kg in total when weighed at the yard in Biggy but as to the corners I don't know but Mark C might.

Hmmm, even if you know the corner weights I'm not sure how it's going to help you? Unlike a four wheel car, you can't change the corner weights on a three-wheeler by adjusting the suspension. The only adjustment possible is to ride height at each corner, and the corner weights will stay the same.

Because the driver/passenger is such a big proportion of the overall kerb weight there is probably some advantage in setting ride height in the loaded configuration -for instance if the car is normally used with driver only, with a little more preload on the right front.

The rat is a slender 230kg!

I have rather soft springing at the front and what I think are over-long shocks. If I'm getting shorter / stiffer units I'd like to know what weights they'll be working with before speaking to the part suppliers about spring rates/damping. Obvs. I'll be weighing it ballasted, but wanted a ballpark to work out if I can use the scales I've got for the job, or if I'll need to source something more robust, as I no longer have access to the weighing pads at work!

OK, that makes sense! If your scales do not have capacity, you could use a stout beam to split the load between the scales and a jack or other support. Halfway should be fine, most scales will take 100kg, and the corner weight will definitely not be over 200.

I've been sitting at home on furlough doing very little except eat gingernuts (if there's a shortage of those at the mo, sorry) for over a year, my trouser waistbands are telling me that with me in the vehicle, I'll be endangering those scales...

Good idea with the beam, thanks!
