hypercoil springs help

[RagingPanda]

I got some hypercoil spring to lower the car and plan to use it for coilover conversion later down the road. 225F/250R 2.5ID and 10inches. The problem I'm facing now is that the spring is too small to match up the spring cap or "bound bumper rubber" Is there a way to overcome this without fully doing coilover? It's a 78 280Z

so you got coil springs and put them on the stock housings with the stock uppers? I guess the spring isn't going anywhere, sectioning the struts and adding the propper collars is actually a pretty quick simple process with a welder and basic fab skills, for the uppers you can use the MSA or EMI uppers taht allow you to not have to cut out the strut towers, you read my strut sectioning post?

ahh...I feel retarded. I'm reading it right now. Thanks again

quick question. Where did you get the parts needed except for the springs and struts. Or did it come in a kit.Sorry but I'm so used to S13 where everything is just bolt in.

lol, well the strut sectioning works on the S13 as wel, you get lowered ried height with increased travel, you can go lower without wearing out your struts ,I bought a kit form Ground Control and weld in camber plates form Techno Toy Tuning, the weld in camber plates are of course optional, there are bolt in available as well but both require cutting out your strut towere, something not everyone is comfortable with, the MSA and EMI uppers are a bolt in camber correcting hat intended for use with coil overs, the GC kit is just sleeves, stops, collars, springs and hats

and if I were you I'd put the higher spring rate up front and the lower int he rear, stiffer rear end will lead to uncontrollable oversteer, all the weight is up front so the stiffer it is the less roll you'll have, the rear needs a bit of compliance to allow it to move enough to maintain grip

Definitely some good info, especially with the drop I want to do to my s30 in the future.

I decided to and read a lot into it. my choice of struts are Bilsteins. Since I already have the springs I wonder if GC could sell me the other parts that I needed( hat, gland nut, etc) instead of buying the entire kit. I don't remember where I heard it from but someone said something about not fitting in a 280z so they changed to the entire strut housing to 240z instead. Do you know by any chance or everything fits in perfectly? BTW: thanks for the write-up...helped me out a lot.

[evildky]

I used 280 strut housing in my build, they are heavier duty, much thicker walls on the tubes but I really don't think it's an issue just what I heard at the time, as for buying ythe pieces, summit sells the sleeves collars sets individually or as a set the afco set was like $60 each, so $240 for thw whole car, plus springs, and the GC kit is $400 and includes springs

I went to summit racing and found them http://store.summitracing.com/...07119. This is another stupid question but which one fits the car with Bilsteins and Hypercoil spring 225F/250R? Is the kit everything I needed? I plan to get Techno Toy camber plates also.

[evildky]

your hypercoil sprints I assume are standard 2.5" ID springs, the free length of the springs will play a part in what length of collar you need, IIRC to run such low rates without binding you need free length of 12", in general I'd sufggest the longest threaded collar you can get because you can always cut it down if need be, the 240 strut housings should be small enought o fit any threaded sleeve, the bilstens inserts have nothign to do with what diameter threaded sleeve you run, you will have to tell TTT whay struts you are runnign so they put the propepr spherical bearing and or spacer in the camber plates,a nd if you decide to change spring rates you can buy individual QA1 springs from summit for about $40 each, vs twice that at GC
