What is the easiest way to beef up the spring rate on the back of a 360 for carrying heavy loads? Is it simply cutting the springs off a scrap car, loosening the bolts on each side and sliding on an extra length of leaf spring?
I'm sure a drifter has done a modification similar, (with lowering).
If you are only loading the car up with a resonable amount of weight then a pair of spax adjustables will do the job. If you are stuffing loads of weight in the back and/or towing then you have three choices 1) add part of another spring in (down side is without any load you will have a very hard ride and imo is not a very good way of doing it) 2) coil over dampers (down side minimum spring rate I can get in 80lbs iwich is a bit ott without any weight in the back - advantage is you can adjust to the amount of weight you have) 3) is uprated rear springs I am going to ge getting some made as the rear is a bit soft partly due to the constant weight of the fuel and tanks.
Have you thought of putting the bikes on the front to even the load out
No on a seriouse note just a set of spax would probably solve the worst of the problems tbh. When you are loaded up you could turn them up a bit stiffer to help. Lowering the front end would also help a little.
Idealy uprated rear springs are the answer. I'm not going to be doing mine for a few weeks (or reslisticly 2 months) but if you want to wait I could price up for having another set made.
To give you an idea of how much difference the spax have made I had to tup a 1" lowering block in to give the same ride height as it was with the originals.
well if you want to make a coil over on the std shock , need to check your local gas/water piper stockists .
some motorbike springs would suit .
i have to say robin hood used to modify dampers like this , and they were totally and utterly useless for the job intended , i still think if you did the job properly would be a good idea .
