What brand of suspension is it? I think some are more prone to sag than others. Just as a matter of interest what width and make are the rims on your car, they look good in the photo.
Yes the ride is better and off road it's chalk and cheese! i was flying over a deep rutted track last weekend and i was amazed at the difference rather than flying over one rut and nose diving and bouncing all over the place it would just hit the track straight and kept going. My girfriend and i were wrapped.
I should add that this is the third set of springs lovell has fitted to my car they say they are the heaviest i can use the others kept sagging 20-30 mm's and so far after last weekend these ones have sagged 10mm and havent moved any further they tell me 10mm is to be expected as a matter of fact it would be good to here what distance you guys read from centre of your wheel to bottom of your guard mine are 530mm right and 520mm left
