Thanks, I knew I had it over dampened. What would you guys recommend for hill runs?

Finally got my YSP dynamic pro's in for about 2-3 weeks now.
Pretty happy with the build quality.
However found that they do not go low enough on the rear for my application.
(yet to see how they look like by loosening the captivity of the springs.
I'm contemplating letting the springs loose and going lower.
Has anyone done the above ^ and what are their experiences?

I have and for me it's not a problem. I did buy some helper springs to keep the springs captive when going low but haven't needed to use them. Eventually I'll probably chuck them in now that I've bought them. If you're worried just be careful when jacking the car up and bringing it back down to make sure it sits in its spot properly. Better still, buy yourself some helper springs.

there is no need for helper springs. you do not adjust height at the spring perch, so the should be captive all the time.

Im the same, i have just installed them on my nc2, and would like to go lower, where did you buy your helper springs? As im worried about springs being loose.

Has anyone bothered to modify the bumpstops in these coilovers or inspect what type of bumpstops are used.

Contemplating getting FCM bumpstops for these coils.

Bit of a thread bump, but instead of starting another...

How are the yellow speed coilovers holding up?

I am trying to decide if i want BC or Yellow speed coilovers, as I think my current shocks are flogged out.
Interest little comparison between the two seen on this thread;

viewtopic.php?f=30&t=60495&hilit=Yellow+Speed

Makes it sound like the BC are a better fitment.

Any other opinion's?

I think I'm missing where it says BC are better fitment.

Search JDMST on BC vs Yellowspeed. You'll find a comparison from Wholesale Suspension who sell both and favour Yellowspeed. Use "JDMST yellowspeed vs BC" and you'll see the thread from 2012.

You can of course get Yellowspeeds from Mania who use them on their race cars.

i've had mine for about 2 years now. no issues with the ysrs. i was also the one the mentioned the fitment variences. but again it was for a car that wasn't a mx5.

Where's the best place to buy them? Anybody got them in stock?

Just to confirm. The rear shocks are now height adjustable le without altering spring preload?

Thanks for clearing that up project r.

So they fit no issues? Accessories where ok?
