hesus2003 Posted February 23, 2013 Share Posted February 23, 2013 i have avo adjustables with 30mm lowering springs in my manta,the ride is fairly hard even with shocks set on soft.i contacted avo and they told me the front springs are 175lb/in and rears are 150lb/in.i see most people are running 400lb/in or so on the front of there mantas/asconas im not really up on spring rates so just looking for peoples opinions on what suspension they have in there mantas/asconas so i can get the right spring combination for my own car thanks in advance Quote Link to comment Share on other sites More sharing options...
Retro Power Posted February 24, 2013 Share Posted February 24, 2013 Hi, 175lb is way too soft for the front unless they are very long springs running a lot of preload, and even then, although they will prop the car up, they will be too soft under driving conditions. As a very rough ball park figure, between 300 and 400lb fronts and 160 to 200lb rears, and probably at the heavier end of that range at the front and the lighter end that the rear. The next recommendation will sound like a bit of an advert, but you don't have to get them from us, there are a few stockists who can supply them, but I would chuck the avos and fit Bilsteins all round. They are not adjustable but they just work, perfectly, straight out of the box. I'm at home so I don't have the damper rates to hand as there are several different options on the bilsteins. I have been fooled by the offerings of several different adjustable shock manufacturers in the distant past, and ended up learning the hard way and buying Bilsteins!! As with everything we sell, its because we have used them, and in most cases wouldn't use anything else. 1 Quote Link to comment Share on other sites More sharing options...
rutts Posted February 24, 2013 Share Posted February 24, 2013 as the bilstein add says " we dont make adjustable dampers as ours just work correctly" same as above 400lbs front 180-200lbs rear should be nice and firm but not too hard. 1 Quote Link to comment Share on other sites More sharing options...
16VManta Posted February 25, 2013 Share Posted February 25, 2013 The spring rate quoted by AVO is more like the rate at the wheel. Quote Link to comment Share on other sites More sharing options...
mantadoc Posted February 25, 2013 Share Posted February 25, 2013 Check the car bump stops are not sitting on or nearly on the lower wishbone spring cup. Often happens and gives whay you describe. 400lb fronts, usually standard ride height or +1" I like these Quote Link to comment Share on other sites More sharing options...
hesus2003 Posted February 26, 2013 Author Share Posted February 26, 2013 yeah think springs are too soft in avo kit,have 2 400lb springs ordered shud sort it Quote Link to comment Share on other sites More sharing options...
jamie077366 Posted February 26, 2013 Share Posted February 26, 2013 I bought some 400lbs standard gte ride hight springs on ebay listed as road/rally for track day use. Imo there way to soft for track, would be fine on road though. I'm gonna cut a coil out to lower an stiffen them up a bit... Quote Link to comment Share on other sites More sharing options...
Retro Power Posted March 1, 2013 Share Posted March 1, 2013 cutting a coil out won't stiffen them! (unless they are progressive springs) Quote Link to comment Share on other sites More sharing options...
mantadoc Posted March 3, 2013 Share Posted March 3, 2013 It won't stiffen them but it will reducer the amount the car drops for a given load. Quote Link to comment Share on other sites More sharing options...
