For all you Megan Racing Coilover Users... Read this
This is a side by side comparison of the differences in just changing springs.... Swift Springs ARE basically the best springs on the market and this is why just upgrading the springs will REALLY help those MR coilovers....
Although this is for mini's they use the same diameter shock tubes.... In the end.... MR Coilver Springs are: ID = 62mm height = 180mm front 200mm rear 8/6 for street coilover series 12/10 for track coilover series Replacement's use ID 65mm (Confirmation from Swift themselves) and retain same specs, but from all the research I have done, S13's weights are lighter, so I would go 10/8's...

you have to contact megan first and see if they are dampened correctly for a 12 springs. on average a spring difference of 2 is ok and no more. so if it's 8 then 6 or 10 but not 12.

Anything that approachs binding will reduce stroke.... Stroke is super important when in any surface. Because swift reduces the amount of coils but still retain linear spring rates, they can increase stroke without changing length of spring or spring rates....
Trust me megan coils suck.... ever lift a car with megans of them and they have no droop or go up a curb and you go 3 wheeling, its because there is no stroke.... All megans can go +/- 2kg/mm as per their site..... Hence I am going with 10/8 or maybe 11/9 on MR Tracks which shipped 12/10..... Also way less unsprung weight for all the springs so it rebounds and compresses during weight transitions much faster. It makes wheels stick to the ground longer....

have stances front and rear, with shorter springs in the front. indeed they are 65 mm. ride is great, i have the track versions.

Swift springs were off by 5lbs. Hypercoils were off by 15lbs. (Yes I know that's not a lot, but still) Swift springs have way less coils, so more suspension stroke. You get what you pay for. Swift Springs are the best you can buy, therefore they are more expensive.

I mean seriously... do people even know the differences on the street.... Like the premie rant said... paraphrase from CodyAce...
Roll in to a meet with his rocket ship and another S14 guy told him nice car. Then the kid asked Cody, what suspension you running, Cody said I built it with Koni's and GC's... The kid said why not put in some nice suspension and look into HKS.... Really.... General Pop wouldn't know the difference.... But its just I thought it was a great article and independent tested via grassroots.... I mean like said, Track vs. General Pop.... I don't dislike megans, but their suspension stroke sucks cause even at 12/10 the suspension really doesn't move and if you look at FEED Rx7, they are using 14/14 and still no complaints about suspension stroke and it settled really nice in the videos I watch of it.... Personally I doubt the shocks are blown and I am sure they still move so it lead me to believe something is wrong with the spring... Lone and Behold this Mini thread which I thought was AWESOME.... and it is....

Also if anyone has any doubts, here is exactly why they are better than others.
Swift Springs USA Videos of on car suspension stroke tests, not just a dyno....... Quote:

Interesting. I though the test/talk was only towards Megan vs Swift.
But as for the price, I don't think 15lbs is enough for most weekend warriors to notice. So Hypercoil is still for me... I would like to know how consistent each companies springs are.

Sorry Mel, gotta read the whole thread and I know its long but good info. But by far, swift was able to have the most stroke in the spring, meaning the ability for it to compress the furthest distance because of the shape of the design. Also was the most consistent throughout the stroke....
I think hypercoils are nice too, I LOVE their hydaulic perches too, but springs, I gotta give it to Swift... One thing I gotta say, springs are like Monitors or LCD's buy once use on different computers, coils buy it and you can use it on all sorts of Dampner... Springs for megans using 65mm, but they fit most of the stances gr+ gr pros, PBMs, I think greddy's, and couple of others too... So why not spend it.... I like PBM's cause they sell the dampner to swap out when blown.... No rebuild, just through the blown away ahahah... Also I would love helper springs on the rear... Keep the car more planted... but eh... those are $$$

Good info. I've known for some time that Swift springs were good. Also, SPLparts sells them in 60 and 65mm ID in various lengths and spring rates for $170 a pair

That's good and dandy that the Swift springs will give you more suspension travel, but really, how many 240s will benefit from them?
Most everyone's car on this forum are like 2" from the ground. If the Sprint springs will give you 4" of travel versus having only 3" of travel with the stock Stance springs or whatever, you're still hitting the ground with your frame first, or your tires hitting the chassis somewhere. So yeah, while they are lighter, which is a plus there already since springs can be part of the unsprung weight, are they going to be $170 for a pair better? For some people that's not an issue, but for some others, that $170 can be spent on something else. Just saying. |

What you guys need are a set of thrust bearings somewhere between your spherical bearing on the camber plate/shock mount and the lower spring seat to allow the spring to naturally wind and unwind as they compress(all coil springs in the world do this due to their geometry). It does make a difference. I've got some Vorshlag upper spring seats with thrust bearings up front and torrington bearings in the rear of my setup. Springs rotate freely and compress easily.

You use 65mm.... Read the thread first...
@Def, I am thinking about those hydraulic perches from hyper coils, but I will look at thrust bearings and torringtons... But seriously, I think springs will help and will make a difference.... But its worth a try, if not I can always reuse them some where else.... $170 a pair isn't too bad.... But keeping in mind about roll center and ride height is huge too...

I 3 wheel with my Megan Tracks all the time, and that is with an open diff. Sucks. Swift springs huh? Cool. Something to consider.

Those things are about $700 for 4, which is how much your whole set of coilovers cost. Plus they need to rebuilt every 10-20 HOURS of use. That's right, you went to the grocery store and back, you just used up 1 hour of your rebuild window. They are absolutely NOT for street cars. Torrington bearings are hard enough to keep clean with flushing them out every few thousand miles - not hard, but it is maintenance to keep them working well. Let me save you some trouble since you seem to actually want a decent suspension, save up for something that's worth a crap and get some GOOD dampers on the car and just sell your Megans. Even something like a Koni 8610 front/Koni yellow or Bilstein rear wouldn't be much more expensive than what you're talking about donig and absolutely blow a set of "modded" Megans away. Please, spend some time at Nissan Road Racing Forums - Powered by vBulletin if you really want to learn about suspension that doesn't suck. Trust me, Megans are absolute junk dampers - there is just no other way to describe them.

I was just thinking about this last night Def.
Torrington bearings.... how hard are they to clean and keep clean? |

They aren't that bad. I just drop my spring perch every couple thousand miles and give them a good spray with WD-40. Seems to get most of the grit out. Then re-oil with a little bit of light machine oil(like All-in-One oil).
My car is not a daily driver though, so it's not a huge issue for me. If I put over say 5k miles on the car a year I'd probably just get another set of Vorshlag spring hats with a thrust bearing integrated into them that's sealed. That's the spring hats on the bottom, but I have the thinner "race" bearing to reduce the stack height.

Yeah I do daily drive my car... as a matter of fact, it's going to pull double duty as a DD and track car, so I guess I will look into the "Vorshlag spring hats with a thrust bearing integrated into them that's sealed"
What do you think about these though Def? Quote:
I'm just guessing, but if these work, they might be a better solution to street cars than the torringtons. |
