It's street/track, so it's pretty stiff for a "street" valving. Depending on the track, I went up to 50% stiffness, but my open diff in the rear limits how stiff I can set the rear due to wheelspin coming out of corners.Wow ... tracking the street set up on full soft that's surprising I can't imagine how stiff the race would b
Hey BDUB, I have a set on the way spec'd out with the race dampers and 10K front /12K rear springs. I won't be able to give you feedback of how they perform on the track until this spring, but you're welcome to come take them for a test drive once I get them installed.R u guys using the stree/performance or track valving?
When I looked on the BW website it looked like there were only two valving options, Street performance and Track. am I missing one that's in between those two?Hey BDUB, I have a set on the way spec'd out with the race dampers and 10K front /12K rear springs.

Based on my research and discussion with Gary @ BW, the firmer of the 2 street varients is probably the way to go for you.
BTW: Did you get the sunroof installed yet?
good to know.According to the ISC website, there are 3 valving options. "Street Comfort", "Street Sport", and "Track Race"

Yes, that's correct.Please correct me if I'm wrong,.......but these are an Asian made Coilover right ?
:thumbsup:Yes, that's correct.
I don't know if your question implies value/quality judgement as is too often the case in forum chat. They're definately a price item, but they seem to get a lot a positive reviews and appear to be good value for money when compared to other options like Billy Sport/Koni / H&R springs or OE replacements. They appear to have a greater market presence and longer history in Asia and Australia. Country of origin can often be a good predictor of quality, but I don't see it as reason to automatically dismiss a product, and for my particular application I think the ISC kits make sense.
Over the course of 2015 & 2016, I'll be completing an SE46 build, while also tracking my recently acquired 330 as much as possible. The car has an all original, 14 year old 145K mile suspension and I'm not ready for the expense of the SE46 MCS setup just yet. I expect to get a couple of seasons out of the ISC setup and sell them when I'm ready to upgrade.
I did struggle a bit with the choice between ISC vs. tried and true Billy Sport/H&R race. Ultimately I wanted the flexibility to play with damping, height and alignment, and learn the effects of those adjustments on handling. For under $1K to my door, complete with camber plates, custom specified spring rates and valving, I figured the risk associated with an unknown brand was acceptable. We shall see.
Definitely do Race School. Sooooo much fun. Practice starts are a blast and the SRE (simulated racing exercise) at the very end is unbelievable. If you attend, I won't be there (I'm instructing at NCCAR) but a bunch of my friends will be there as instructors and racers and I was just hanging out with the chief instructor Jason Crist today (and most weekends). He helped me install the ISC N1s that this write up came from.This is Great info.. I used a AIM this past weekend for the 1st time to start checking my times to dial things in a little better and was doing 2.13's & .14's but I'm on stock dampers with HR & springs & street tires.. I think I'm gonna have to pull the trigger on these.. I'm thinking about doing the BW RS in April so this looks like a good segway.. Thx again for sharing..
I have solid fcabs (well a thin delrin insert) so my feedback is insanely more bumpy than oem or poly fcab* That said in Winter time (thank goodness it's over for where I live) it's like a 4.5 out of 10, they get pretty harsh. Now that weather is warmer they're like a 7.5-8 out of 10. On track I'd give them 9 out of 10. Overall for the price they're great. I love them. I think you can order different spring rates when you get them so ask Bimmerworld when you call for what they recommend.Still enjoying this setup? How would you rate it for street use? I'm in a hurry to get some coilovers for my build project and this might work well on the touring I'm building if the rear spring rates can be adjusted.
Yes I know.. sorry, I didn't have any available at the time.Some real pics of your plates would help us out.
Is the length of the slot the same on each plate? It could just be that they changed their marking scale and you happened to get 2 different markings.Yes I know.. sorry, I didn't have any available at the time.
My drivers side is what I am having issues with.. standing behind the car the Camber angle just isn't as aggressive as the passenger.
It's very clear that they do not match the image you posted Jabela
