Hey guys, new here, surprise to see people still remember the B12/13. Here's my problem maybe u can help. Does anyone notice that ALL B12 with rear stock suspension seems to be lower then the front. I have a stock 89 2d and the rear suspension use to be even with the front. After several time of carry heavy load to the airport the rear sink more than 1 1/2 inch at least. I did the press and release testing method of the rear suspension and the rear doesn't rebound as fast as the front(not even close).........that is when I press and release the rear suspension the rear just stay down and move up very slowly unlike the front which rebound the instance that you release. Could it be the spring cause the rear spring seems to be smaller or it's just the shock? Thanks
