fitting oem spring on aftermarket coilover

Recommended Posts

I am having trouble figuring out a way to run the factory 370z springs on a coilover with a lower spring perch meant for 2.5" springs. The z has 3 inch lower diameter spring increasing to a 3 3/8 upper. If i knew someone that could fabricate a cup with a 2.5 inch inner diameter or create a threaded perch with the the larger spring in mind. I could run a big washer but would have to find someway to keep the lower spring isolated.

 

link to what the factory setup looks like.

It would probably be more economically feasible to buy properly-sized springs with a rate similar to stock.

 

I'm no spring/suspension expert but IIRC 2.5" springs are standard and you can get them in many lengths and rates.

The first result. I have no knoweldge about this company, it's just an example.

You're going to do more harm putting a stock spring on a coilover body valved for a completely different spring rate... aka your car is going to handle like shit. I suggest you run the stock suspension, or simply change classes.

Motion control suspensions 2 way non remote. http://www.motioncontrolsuspension.com/products.html

 

If I am understanding this correctly, those are 18 way adjustable shocks, meant to replace the factory shocks/struts and use in conjunction with a spring combo. They have a note about including springs, but obviously you are trying to avoid this. Mechanically speaking is those are designed to work with a factory replacement spring then your factory springs would "work"...

 

But as just mentioned 18 way adjustable shocks seem...pushing the rules of the SCCA class you may be after...I could be wrong.

No, those are 2 way adjustable shocks with 14/18 settings for compression and rebound, respectively. They're legal in the stock class; until recently, even the remote-reservoir versions would have been legal.

 

Adjustable spring perches are allowed as long as they're set for the stock ride height.

 

That's all assuming he's talking about SCCA Solo. In any case, I don't have an answer for the OP. Have you tried contacting the company?
