jumpman2334 Posted November 22, 2009 Share Posted November 22, 2009 quick ?, search and couldnt find anything. as of now, i planned on putting an rb20 or an rb25 in my 78 280z within a few months, but i planned on buying coilovers in a few days. so i wanted to know if i bought coilovers what would be a good spring rate? i was told with the l28 motor, 200-250 would be enough. but i just wanted to know if the rb motors use the same spring rate as the l28 motors. and sorry if this should be in the suspension section. thanks.

J Taylor Posted November 22, 2009 Share Posted November 22, 2009 I don't think the rb is going to change anything to do with the suspension setup. I'm running (I think) 225 front and 250 or 275 in the rear. Been using this for 8 or 9 years and have been happy with it. JT Quote Link to comment Share on other sites More sharing options...
