Guest Magic Posted April 3, 2005 Share Posted April 3, 2005 My turbo upgrade to my NA l28 has been accomplished and with 200kw at the wheels, FMIC and a few other turbo bits adding some more weight to the front. I think its time to look at upgrading the rest of the car. Some of the people I have talked to are runnning hard 300lb springs in their racing 240/260s. Im not too concerned about comfort, but I would love to have something that will handle. (I plan on getting some camber plates & changing out all the bushings with plastic then looking at sway bars). What are you 280z guys using and how do you find it? Quote Link to comment Share on other sites More sharing options...
johnc Posted April 4, 2005 Share Posted April 4, 2005 Your choice of spring rates depends a lot on shocks available to control the springs. The non-adjustable Tokicos, Monroes, etc. are fine until you hit psring rates over 175. The Tokico Illumina is good 150 to maybe 250. The now discontinued Koni 8610-1149 is good from 250 to 350. There's also a Bilstien application that is comparable to the Koni but I don't know its part number. For spring rates over 350 you're looking at a custom setup. BTW... the most important question is: What do you intend to do witht eh car? Quote Link to comment Share on other sites More sharing options...
