A longer spring of the same rate will still compress the same amount. All it's doing is changing the location of the collar on the sleeve.

 

 

If it will compress the same, how will it extend more?

 

I'm using 7's. No probs. Monster truck not found. See MATG thread for recent pictures.

 

I don't think i'd say that "most other" setups run 7" springs. I think 7" springs are the exception, not the rule.

 

No, because it's not a helper spring.

 

7" springs and NA shocks. I'm a weirdo.

 

6" main springs with 4" tenders on MSM shocks checking in!

 

How do you guys keep the sleeves from rotating when you must adjust higher than 0 preload on the spring? I was thinking of drilling a hole at the top or bottom of the sleeve and putting a set screw but I'm afraid of starting a crack or something and having the sleeve peel like a banana on me.

I'm working on getting my fenders rolled and would like to set the height to the top of the range to avoid fender-tire contact, but can't seem to rotate them ******* higher. I lifted the car and I can rotate a few turns after getting some preload, but not much more than that, still sitting pretty low (I mean, not SLAMMED obviously but not the gap I'm looking for).

I did tape as much as I could between shock and sleeve, the max I could put in and still have the sleeve slide on, I also added a thermostat oring and some tape under the circlip to keep it centered from the bottom, so it's snug, but not locked.

 

I've never really had a reason to do that, so i can't tell you a great option. Other than hold it harder?

If my springs were pre-loaded, my car would be a monster truck.

 

..perfect timing... I just dropped the car on the ground, here's the setup:

90 NA
B8 HARD-S (NB) Front NC12-34-700D, Rear NC12-28-700D
NB top hats all around, stock NB top hat bushings.
ES 9.6103G spring top bushings
Allstar sleeves on stock C-Clip grooves. Rears trimmed 3 threads to drop below the shock body top, fronts are good without trimming
Front is 8" 450lb, Rear is 7" 300lb
5Xracing 36mm blue bump stops

On the bench, I just snugged the lower perch up to the spring then installed. Initial ride height is way high:
7-1/4" Rear, 7-3/8" Front (pinch welds)
15" Rear, 15-1/8" Front (fender to hub center)

Shooting for 13-1/2" Rear, 13" Front (don't bust my ***** on that, this isn't a hard core anything plus that's basically all I can get on these sleeves in the rear).

So, obviously I had to lower the perches, now I have 2" of gap at full droop. I feel like the cheapest solution is helper springs and that's about it? Who's the current fav reseller online? Need springs and the alignment washer thing in the middle.

 

The cheapest solution is to simply quit worrying about the spring being unseated when it's jacked up. This isn't a problem.

 

Ok, fair enough. But won't I see unseating when I unload the suspension? I'm taking this car to the track in 3 weeks and there's a point on track where I can probably unload it completely. I don't want to get there and have **** break/bend/get all jacked up/etc.

 

Pssst......every single spec Miata on the planet has it's springs dangle. I've never heard of or seen a problem. Take a look for yourself.

Whelp, I'm lettin' 'em hang. Achieved the ride height of 13.5"/13" limited by the front lower perch as low as it can go. If anyone has a pair of 7" 450ish pound springs, hit me up.. that'll gain me 0.75" which is when the rears are at the lowest point.

Now if it would stop raining, I could actually try them out......

 

Thanks. Was going off what I read on this thread and across the "collective internet" on this but I'm probably wrong in typical n00b fashion. Since coil bind isn't really an issue with the 6' springs, i'm planning on going that direction and since i have the adjustability in the sleeve I can get to my desired ride height without having to go "max low" or close to with a 7" spring.

One stupid question, the Maruha top hats fit in the front? I think i read the ISC top hats require opening up the front hole to accommodate them, but I don't think i saw this being an issue with Maruha top hats. Assuming I got this right, will just order 4 of them since they're cheap enough. Saw your post about 15 pages back saying they're about right for the fronts but the rear depends. Going to measure everything over the weekend and confirm if they'll work for me.

 

 

Awesome. Figured they would using the same "it's a modified stock tophat" logic. Brb, going shopping.
