I am looking to install a set of coilovers in my G35 Sedan, that will mainly be use for track days/time attack with the occasional drag racing... I am trying to decide between KW V3's or Fortune 510's w/Swift Springs... The Fortunes are totally customizable from the builder in the USA, I have spoken with a rep a few times and explained my use for these, they recommend I go with 13k/10k springs... KW's spring rating is not 100% known and they are progressive, however they have a great rep for being a great addition to our cars... ANY input would be a great help and please only useful info, not just which you "like".... Not being am a-hole, just want to make the BEST choice possible as I have already spent a lot of $$ on this build with quite a bit more to go!! LOL.

Also, the KW's I can get for around $1700 vs the $2175 price tag on the Fortune 510's....

Thanks in advance!!!

I've used the Spec Z KW kit and they are a reasonable package. I've never heard of Fortune 510 in either SCCA or NASA racing and would be very leery of a product or company without an established motorsports reputation.

 

The name of the company is Fortune Auto, most people opt for the cheaper 500 Kit.... There are a few people on here or g35driver forum that run them and all love them and the Evo/240 Guys also say they are a really good kit..... I just want to make sure I do all I can to set my car up to perform at its best..... Thanks for the info Sir!

 

KW will hold it's value better and I trust the KW damper.

 

Stock, until you yourself know what you want and can demand out of a coilover.

 

I have quite a bit of time behind the wheel, in my Other cars.. .. lol. However I know that every car is different... I have had this car on the track 4 separate events and that is what made me go ahead and decide to build this car when i was done with my M35.... I have been doing all the Mods and engine building and I am ready for the suspension now..... It is just a hard decision..... KW V3 is a proven product on the street with minimal track use, I plan on this car to be 85% track/autocross-- 10% Drag Racing-- and MAYBE 5% one the street, that's why i was looking into a combo that would be good on the track..... Also I have used and also read on here a few people are going with KONI Yellows with Swift Springs or another performance Spring choice, Do yall know how effective that combo is and does it compare to the KW V3's on the track?? Also if yall have any input or advice on another Shock/Strut Combo and with what springs?? Thanks again Guys for the help and Input!

Not at all..... I have seen some info on these True Coilovers.... Just not sure if they are better than the Gen 5 510's.... WITH the Swift springs of course.....
