What difference is there between autocross and road course usage? You might want slightly higher spring rates to work tires harder in autox, but a "good" setup is going to be very similar on both of those applications.

tein super drifts work fine for me, and the ride is actually not bad.

our school's engineering or aerospace department has a shock dyno. The idea of testing several different brand of dampeners and writing a full report on the test has crossed my mind a few times.
I've been thinking about my senior design project for next year, and perhaps i'll do something that involves the testing of a couple different shocks and the full range of settings.

^^^ YESSSS! Do it!
I bet we can have some retailers and possibly members 'loan' a couple coilovers... the problem is usually you want just the damper on the shock dyno, and people aren't going to want to disassemble their coilovers (I'm guessing). Anyhow, an apples-to-apples comparison with soft, mid range, and stiff settings on a bunch of coilovers needs to be done

i didnt see D2 on the lower end coilover range.... you can usually get them for about $900 shipped and they outperform anything else that ive seen in the cheaper category

So I began looking into another suspension company based in the Netherlands: www.ast-suspension.com.
Seems the founder used to work for Koni for quite a bit of time and started his own company. I emailed AST USA because I heard Aragosta coilovers were made in Netherlands by AST suspension but had no solid evidence. Apparently Brian @ AST USA verified that with this email he sent me: "Jason, Single adjustable is $1750. Top mounts are optional. Fronts are $385 Rears are $230. 3 way shocks come with top mounts. Doubles have not been created for the S14, but we can probably do them. Struts and shock doubles are usually around $2650. We can use whatever spring rates you want. Topline is AST's dealer in Japan. They didn't want to use the AST name so he came up with Aragosta." Brian was very fast at responding to my emails and inquiries about AST coilovers and now that there is AST USA, stateside support is readily available. Sounds like a viable but pricy option. AST Suspension might also be another way to go. |

I have a semi-decent list up at http://driftkat.com
A list of exhausts too. It's definitely not complete.

Topline is a dealer of AST shocks in Japan. The guys called the AST coilovers in japan, Topline Aragosta, instead of AST Coilovers because they didn't want to use the AST name. This is how I understand it from Brian's email. |

www.aragosta-suspension.com And then there's Topline. http://www.aragosta.co.jp/ Judging from that e-mail, Aragosta is either owned by AST, or there are two different Aragostas. The former makes a lot more sense. In any case, it doesn't matter, good shocks either way. |

ASTs are nice, but one thing that concerned me is it seemed like they were using similar valving/same shocks for very different applications. Not so much a problem as long as you can get things more in line with adjustments, but on single adjustables I'd be wary. I never realized how much difference changing the bump can make always having single adjustables, but with 8611s up front 1 click either way makes a huge difference in how the car responds. |

Without finding that plot again, the racing gears had the right shape, but they were way overdamped in rebound and, I think, overdamped in compression as well. So unless they were for something like a 3500+lb S13, they wouldn't work that well.

I have a simple question about pillow mounts, are they inter changable from coilover brand? the reason I ask is I just got a set of the tanabe sustec pro s-oc 2 and tanabe says that they are discontinuing them so they are no longer making the pillow mounts for them. Could I simply put some tein/hks upper pillow mounts on instead?

yup i was gonna say he didnt include dg5's, and i got a review on these from formula d driver joon woo maeng, he says he likes them a lot, he said that he could feel the difference from his last coils (no idea what they were), but anyways for those people wondering about the dg5's i guess there a good buy? 2500 better be a good buy lol

when people give reviews they also dont say what they have for the rest of the suspension and how it is set up etc alginment settings that makes a big difference in the way the car handles as well

The ultimate coilover thread would also explain signs and symptoms of blown, leaky, bad etc. coilovers... and also explain spring rates (comfort-full race)

I got a set of Kei Office and the ride makes my tail bone hurt. I always feel violated but like a cheap whore I always ride it again.

Spring rates don't play as much into comfort as damping does. |

dg5s..
should i post agian? what the hell i talked w/ my friends at FD who run DG5 pat, chris, joon, justin...well not about DG5s just shooting the shit but i have talked w/ them in the past before i ordered mine up. make sure no gimicks all them absoultely love them pat did mention on full soft he can push is car down a good amount and on full stiff nothing forsberg did say the adj is incredible. clicks make a difference u can set it stupid soft and it is soooft. or hard and it extremely stiff. anyways most wont spend the money but those who do, wont be disappoint i test mine when my car is running in 2 weeks.

Be careful with used k sports the valving is not the best from my experience I have them on my daily and have had no issue. but if you are going to track the car i would recommend at least stance. Megan are also another budget coil over but imo the track series with 10/8 spring rate are to stiff. just my opinion

What about some of the higher end k-sport? Does anyone have any track experience with those?

SicBastard, about my earlier post about Ohlins being designed for high speed dampening, I apologize because that statement was vague. I was speaking with a Ohlins, Motons, etc. (high end stuff) dealer in Sonoma, I forget the name, and getting feedback which suspension I should go with. My requirements were having my car to be daily drivable and competitive on the race track. Although those two requirements are unnecessarily intermingled, I wanted to go with something I can tailor to my driving style now (auto-x or occasional track days), and as I progress , eventually turn my car into a race car, I could use the same suspension without upgrading. Of course I would have to re-valve if I were to use different springs. Anyway, back to the Ohlins, from what I understood from the shop was that the high speed dampening would not be beneficial on highway roads due to the amount of pot holes and bumps. From what I have been told by Brian at AST is that high speed compression is taken into affect when the damper moves greater than 4in/sec. In retrospect, and as I was told, was that is too much rebound and compression dampening (single adjustment) to soak up the bump on the roads to be daily driven. Hope I've made sense in my slur of things.
