Havent heard much about people doing it. But if you have what have you found out? Which corner is heavier? What was height difference on all 4 corners? Approx how much did you lower?

I've just lowered mine approx 20mm on 12kg f +r coilovers. Have noticed FL and RR sit 4mm higher then opposing diagonal. But rear spring is higher in LR side by 3mm. Didnt have time to adjust more will try in a few days before it goes in for adjustment and alignment.

Thanks.
 
Great vid Phil. @arnies_gr mine is in for this next week but on softer springs so I will let you know.

My OEM bottom of rim to arch heights were 615mm on the driver's side and 617mm on the passenger side with me not in it and half a tank.

By the way.
The height difference on the front drivers side (depending on the suspension your running) will vary ~3-5mm with an 80kg driver in it or without one.
So make sure you measure always with or without a driver. 😁

That's what I thought, but have seen vids etc with no driver visible, possibly had weight in the car to simulate ?

If you are going to corner weight a car you need to be able to adjust the anti roll bar so there’s no preload on it. Adjustable length links are needed.
Another issue is that the scales need to be level, you need a flat floor to cornerweight a car. The scales should be sitting on ajustable pads and then use a flat bar with a spirit level placed on it to ensure the scales are exactly level with each other, a workshop floor will not be exactly flat, a few mm out on the floor will make a huge difference to the scale readings

Indeed! All in the prep.

I fashioned some adjustable drop links for mine.

To add: the higher the spring rates, the more it matters. A few mm difference on 3kg/mm springs is hardly noticeable, a track car with 20kg/mm springs, a few mm out can really ruin the cars handling...
 
Mine wasn't as bad as I thought on original suspension (100kg driver). Certainly can work with front cross weights while maintaining decent diagonals

something to note regarding adjustable drop links...there's no L&R adjustment required when relaxing a roll bar so you only need one adjustable link per axle the other drop link can simply be the original factory fit item

on the GRY the rear drop links are so short its unlikely to find an aftermarket of smaller size so in this instance you'll probable need to fit 2 adjustable aftermarket items
