JCrim's Road Racing Thread - Stay Tuned!
i'm still looking into those rear springs... not finding much except that the straight or concave (hourglass) springs are good for packaging concerns (takes up less space)...
i found something that said that straight springs hold their rate better through their stroke than shaped springs...
my feeling about the rear springs in the fit, and on my ptgt, is that the convex/barrel shape is there so that as the rear axle seat changes angle to the upper seat at it goes through its travel, the shape helps the spring stay seated better...
kinda like how if you take a small straight spring, grab the top and bottom, and pull them close to each other, it wants to shoot out of your hand... my feeling is that it's something like that... but i've yet to find anything out there that says it...
i think ideally, if you found another car with a torsion rear beam suspension, but that's heavier or more sporty, you should be able to swap springs... ala this link: Browser Warning
i'm still going to do some more searching b/c i'm interested in finding out an answer... i'll keep you updated...
but speaking of updates... ?!?!

My current status with the swap and car is the nut cutting part.
I need to get a cheap DD car first or rock my buddy's jeep with no AC until swap is complete. but if i ever want to go full race, i will need a dd anyways so why not just get a comfortable ac car now lol.
next comes the fit tear down.
btw, you coming to the meet at MSR houston this weekend?
i think this is the best i'm going to find:
2. Why Swift's longer springs (some of 10" and longer springs) are trapezoid
designed?
We designed our longer coilover springs for one purpose only; to minimize the chances of the spring from bowing. (Just imagine a spring that buckles as your knee would buckle). That is why we picked the barrel shaped design instead of having a straight shaped spring. Say you have two springs that carries the same free length. One of the springs has more coils wound then the other. The one with more coils will not bow as much as the one with fewer coils. However, when you add more coils, in turn you add more weight while limiting the available stroke in the spring. Swift choose a different approach. We decided to develop a spring that has a barrel shape (Smallest circumference gradually increasing till the center coil of the spring, then decrease in the same ratio). With the barrel shape design, it allows us to utilize fewer coils on the spring, as well as less weight, and also allows us to keep our accurate liner spring characteristics.

Barrel Design
Isn't the barrel design heavier? Not on Swift. Still one of the lightest!!
All of Swift Standard 10” and longer Coilover springs are barrel design; the design is to solve all spring bowing problems. With bowing springs, you can expect spring rate inconsistency, and rubbing against shock body that would lead to damages on the shock adjusting perch thread. (Except Swift Drag racing springs)
One approach would be to increase the number of coils on the springs. With more coils on the spring, you will experience less bowing motion. This is the easy and cheaper method to solve the issue. But the downside of this method is a decrease in suspension stroke, increase in un-sprung mass, and will effect the overall movement of other suspension components.
Unlike others, Swift designed barrel springs with one common rule, which is all the barrel springs design have a maximum of 4” OD. Because most other manufacture do not design their barrel springs with this rule. Most of their barrel springs outside diameter will differ from one rate to another. This creates a hard time for racers to test and see which rates will fit and which rate does not. A heavier rate spring tends to interfere with the suspension A-arm or other suspension components.
Generally speaking, the barrel designed springs tend to be heavier in weight than straight shape springs, but Swift coil springs will never have this problem because of our world leading coiling technology .

basically all they have to do is say yes or no.
swift, can you look at my rear skunk2 spring design? can you replicate it but with my own spring rate request and your product material and design of your company. thanks.
lol
Koni 8041 Race shocks + Koni Sleeve + Hyperco springs, 700lb/in all around.
Fap.
i know... right?
deliciousshow up in a fit like a baws. they would be like "what is this clown doing?" then "OHHHHHhhhh snaaaapppp" then I wake up from dreaming. haha
let me hurry and find a new DD and ill tear the fit apart. got 1500 saved for a dd. want something worth having and no more than 4k. i think its going to be an integra.
amen brethren.
you know i really thought about them. but i wanted to attempt swift first. man, swift really sold me on their information haha
is it like super unlimited? I can have a k swapped, 9" wheels and race in a class? is it road course or autox? would be dope! however, I am lame as hell at autox haha.
show up in a fit like a baws. they would be like "what is this clown doing?" then "OHHHHHhhhh snaaaapppp" then I wake up from dreaming. haha

pretty much hyper coil is liek the american swift, minus the material they are made out of.

And FF Battle is a track event at Fontana in California.
For a daily, get a Mitsu Galant man. Do it.
like a sponge. you would be surprised how much data i gather. And I'm sure the military amplified this due to the training of abnormally high attention to detail and teaching me air traffic control. High speed, low drag!
For FF Battle, you'll be limited to whatever size tire the official tire sponsor can provide. For 15" wheels, the only size available was 195/55/15. The official tire sponsor was General Tire and the tire was the G-MAX AS-03. It's an ultra high-performance street tire with 480 treadwear. Not sure if General will be the offical tire supplier for the next FF Battle. I'll keep you updated.
