Fortune Auto 510

Hey Guys
switching over from kwv3's to fa's and i want to know what is the most aggressive spring rate combo I can go with for the most agile/nimble handling?

the car is mostly for the track and even on the street i dont mind the stiff ride, so please let me know the most aggressive I can go

also the only aero im running is an evo-r high wing if thats even considered aero and no front lip yet but i will be soon

car weighs 3,250 pounds wet no driver, and even if i gut the rear I will add a 4 point so the weight distribution will stay the same

thanks in advance

Hotrodz runs the Fortune's. He'd be a good guy to talk to

This was a great help, still not sure if I want to go true type or stay divorced. If I were to stay divorced, do you know where I could read up on that

OptionZero · 05-03-2021, 01:10 PM

doesn't that thread already tell you everything you need to know?

The main, practical difference is the calculation in spring rates.

If there's some theoretical advance in the geometry, you'll never feel it. Only the highest levels of TIME ATTACK!!!! CHARRRGE! folks would know

Additionally, and this should be obvious, but . .

True type vs divorced type requires different hardware. The "true" type will ditch the mid-link bucket because there is no spring to seat there, so you replace it with a toe link.

As your current KW V3's are divorced type, i assume you already have the SPL mid-links. Instead of swapping them out, getting divorced type will let you keep them

As always make sure you get the correct spring ID to fit the SPL buckets, which i believe is 65MM

LASTLY

If you're going to be pulling your coilovers and ordering from Fortune Auto, I would stroooooooooooongly recommend grabbing the cup kit with it. They'll send it to you pre-installed, at least for the fronts. My biggest regret is not getting that Aragosta setup all together at once

Hotrodz · 05-03-2021, 02:50 PM

Great stuff here and the thread I started on aero and suspension balancing. I would say if you are going to stay divorced and you don't have mid links get them and keep your KW 3s. You may need to get stiffer springs. That said standard fair on divorce type 12k rear 14k front. If you go true type your rear should be close to OEM spring rate 7 to 9k so your wheel rate is not out of wack. Front can stay 12 to 14k.

OZ is right if you want to do more than shoot from the hip find a shop that specializes in track cars. They may be willing to give you some solid numbers. The guys at Professional Awesome Racing helped me out a bunch and did not charge me for their advice like they would do normally. I bought several hundred dollars of their stuff for helping me out. I would call Will at WRteknica and see what he has to say. He is a Nissan guy and knows our platform well. For a track car he will recommend true type.

he's in Socal, it seems like there would be no shortage of places that will help you set up your car if you give them money

Art of Attack, Dogfight Garge and you still can't go wrong with Westend Auto. Go see Amir, RS Future he is a KW fan! Like you said no shortage of shops to choose from and all of them are in to time attack in a major way!

Thank you so much for thr DM as well, the race shop that basically did everything to the car is JMP. issue is theyre mostly e46 guys and told me I can go up tp even 20k up front and then accordingly in the rear. wondering if thats too much

v3's are just too soft for me

thank you for that, and i will for sure grab the cup kit too. Itll for sure come in handy especially as were running it so low

The main reason im still iffy about true type is only because the other changes that need to be made like you said. and im wondering if it is even worth it at the driving skill i am at right now

Hotrodz · 05-04-2021, 05:04 PM

So you have a car that is more suited for track and you are going to spend money on something that is not horrible but there is better. True type coilovers are the way to go. The setup is no more difficult than doing mid links and is less expensive. You should get to know some of the folks that participate in the Nissan Challenge as there is a ton of knowledge there. Malko or eagle here on the forum is someone you should talk to. DM him about his setup. He is one of the fastest guys in his class and overall. He runs Powertrix coilovers and they are true type. They are a very good product for the money. If you are over running your KWs then you are good enough for a true type coil. I am a suspension junkie and it is worth doing it right. You have a ton of experts close to you. Find one a follow their lead. Another good shop is Rockstar, they are a Feal dealer and very good with Japanese cars.
