My shop is right next to the ISC guys in Bow NH and these are some pretty nice coilovers, I rode in an E30 that had these on the track a few months ago and I was pretty impressed with them and can't wait to get them in my car! granted its still spread out like legos on the floor of my shop

Let me know if you guys have any questions or who wants in!
Thanks,

Spring rates?

[sharky]

So rebranded BC's, which isnt a bad thing.

[mccor023]

Sorry for the dumb question, but are te rear shocks 2 piece?

[E_Before_I]

Spring rates?

ISC does offer custom spring rates but they do come with a standard spring, which I will get the specs from them in the A.M. sorry I didn't put them up there!

[E_Before_I]

Sorry for the dumb question, but are te rear shocks 2 piece?

Not a dumb questions, its a little different setup than we are all used to, the shock itself is a threaded tube, it threads into the lower half of the rear shock and then has the lock nut.

[superleggera]

very interested but I'm assuming the front struts will need to be welded to the spindles?

[superleggera]

also interested in the standard spring rates. if I need different spring rates, how much would they be?

[E_Before_I]

The front struts do need to be welded, I will be putting mine together here shortly so I should be posting some pictures of it. Its a threaded insert that you weld on and then you thread the strut into that. The last set I put together went on pretty easy. I'll have to ask about the other spring options, do you know what your looking for or just seeing exactly what they offer?

[DTFE30]

I've had mine since march.

Standard Spring Rates: 185 lbs/in Front 380 lbs/in Rear

I'm interested but I need more info on the race spring rates or custom options. The standard rates are way too soft for me or any casual track use.

What would be an ideal spring rate for you? I'm talking to them tomorrow about what they can get, and if I had a number that people were looking for it would be a lot easier so if anyone has what they are looking for let me know!

[FLG]

Im running bc's but just to chime in on spring rates. Id say most guys who want a stiff ride and who track their car would want rates around 400-450 front 600-650 rear. Standard rates way soft, almost identical to H&R spring rates.

[E_Before_I]

I'm sorry all, I misunderstood what they told me about the spring rates and did the conversion wrong, I was changing it from kg/mm to lbs/in. The spring rates for the e30 are 504 lbs/in front 504 lbs/in rear, I was told 9000k was the spring rate and I'm thinking to myself... ok is this a spring constant? what is that wheres my lbs/in. E36 is 448 lbs/in front 560 lbs/in rear and e46 is is the same. Once again all sorry about the confusion there!

[DTFE30]

Here is the fronts welded up. I did it back in February when I was testing them out. Identical to megan racing.

You should really find out the spring rates they can get. I went back and forth for 3 months before they strait up stopped responding to me and left me hanging with 10k front and 9k rear springs. If you look at any real setup you need at least 150-200lbs/in more in the rear based on the suspension geometry.
