yeah it was actually one of your topics i was reading. have seen alot of kit on the market but most lower by 30mm or more. would mv6 springs or springs that lower by 15 - 20mm go with the stock elite shocks or would they need changed as well. you say the self leveling is still ok with this.
Sounds like your after mv6 lowered sports chassis to me...? Gives 15mill drop over stock, firmer less body roll but not overly stiff. Also, on my old car i kept the self levelling, which in my opinion works fine with firmer springs though you may need to fiddle the ride hight to match the new rear springs. All perfectly doable, and the Springs and shocks are on trade club, pm andyc on here for parts and prices etc.
Having said all that, I'll be fitting irmscher springs and bilatein b4 shocks in the spring. Giving 30 mill drop.
Er... not sure if that combo would physically work or not tbh, but I certainly wouldn't entertain the idea. There will be different damper settings in lsc shocks and the lower ride hight will mean bump stops will be 15 mill closer to using up all the travel on elite shocks with lower springs. So hit a bump on the brakes and the suspension could be compromised, although in practice I can't say what the physical difference is but lsc shocks will contribute to less wallowing and body roll. So that's the front.
... Rear, you raise a logcial point re self levelling shocks and lower springs. My case for keeping them was based on a couple of things, one I intended to tow with the car, but that aside, plod use them on on mv6 lsc for vehicles with heavy load, gun cars and the like, so they must work at a lower ride hight. Plus I didn't want any grounding issues with a fully loaded boot. And it has to be said, I didn't need to buy rear shocks, so cheaper as I already had sl shocks fitted. Others have used stock springs which are firmer than sl springs with no issues, and it seemed to me firmer springs would give the damping in sl shocks an easier time.
Rear will not take the punishment the front will on the brakes, and oddly the back only dropped 10mill anyway iirc, and the self levelling seemed to adjust to the new night on it's own with put the need to tweak the arm on the sensor, or maybe it's not that accurate?
Over all I was well happy tbh. Although I could still tell the rear damping was not exactly the sMe as the front, I felt that was a small price to lay to keep self levelling.
