interesting. btw whats the warranty like on the coilovers?

 

We offer a 1 Year Standard Warrenty

 

I believe Dan said 1 yr unlimited miles.

So now I’m unsure of the spring rate change. At first Dan said that the 380/380 set up was great and it would be as smooth as H-sports with stock shocks. When I asked about what setting he was using to make this statement I did not hear what it was. Then every one chimed in that the rates would be way to stiff and they were changed to the 280/320 rates. Not being a subject matter expert would these new rates be good for someone who doesn’t track his car very much or at all but would like a firmer then stock suspension with the benefits of coilovers at a good price?

Maybe this is not a good comparison but how does the Bilstein PSS9 Coilovers compare in their spring rates?

Don’t get me wrong I still want to try these out as they do look to be the best value for the money for all of the features you get with them just want to know if I should go with the 280/320 rates or ask for the original 380/380 rates.

 

For someone who doesn’t track his car very much or at all but would like a firmer then stock suspension with the benefits of coilovers at a good price,
the 280/320 will be more appropriate for your application than 380/380.

 

Thanks that's what I thought. I just thought it was interesting that Dan said he thought that the 380/380 set up was great and it would be as smooth as H-sports with stock shocks. This is what I was originally gonna do.

 

I think that the 380/380 setup is good still. But I wanted to build a kit that will satisfy the most users. That being said, the 320/280 setup will do that. I know that there are some more serious track users out there. That is why I will offer a rather inexpensive upgrade to the higher rates of 380/380.

If you want this for agressive street driving, i'd go with the now standard 320/280. If you want it for track, you can use 380/380. The upgrade cost should only be about $150

 

Hey Dan,

Kenchan wrote 280/320 and you wrote 320/280. Which is the correct?

Given current info, will these fit a 2006 mini?

Perfect! I assume it's just a set of 380 springs to replace the stock ones. A question that didn't get answered and asked again by SCMCS:

"Was this concern posted by onasled addressed?-"

"If you are still in the tweaking phase then consider the relocation of the front drop link mounting tabs. Being that we will need adjustable drop links with these there are repeated reports that the lowering tends to bend the links due to increased angles. Consider putting this tab as far towards the rear of each strut to help this problem from occurring."

This could affect longevity, but I assume you have addressed this. Thanks.

280 Front 320 Rear

I am not aware of changes to the 2006 suspension, so I would say they will fit.

 

Pilo,

Just for ultimate clarity...

So the people that said they were in with the 380/380 will they get the 280/320 and then a free set of the 380's. Or will they get the coilovers with the 380/380's?

I know you said in an earlier post that people that commited and wanted the 380's would get them.

 

I'm not certain, but I think he said that anyone who committed to the group buy before the change was made would receive a set built to the final standard (i.e., 280/320) configuration plus an upgrade spring set. I believe he also said that only one of us had officially committed that early.....

 

That statement is exactly why i'm looking for a very clear answer, i'm pretty sure i got in before the change. So i'm hoping i get this deal.

 

As per this post these were the folks that committed prior to the final spring rates.

Who is actually looking for the stiffer spring rate?

 

At this moment i'm in that boat, i think the Group buy thread has each person specifying which springs they want. I like a stiff street ride because i have pretty smooth roads, and i'm trying to become more involved in AutoX/Track days every year. So i want something that will be VERY competative.

So if you said the 380 was smooth enough for NJ roads and potholes than i can imagine it'll be a dream cruise on Miami streets and highways.

 

What would help me decide this is if you can say how you had the dampers set up when you had the 380/380 springs on your car and you said they were like H-sports with stock shocks. Were that set to the softest setting or some other setting? Meaning that they would be like H-sports with stock shocks at their softest and get firmer from there.

Also with the 280/320 springs and the dampers set at their softest how would they feel and with the dampers set at their firmest how would they feel? I know you may not have a definitive answer to these questions but a generalization would be nice to know.

 

typically (generalization) at softest you'll get undulations and firmest you get hop.

Comfort also depends on what wheels/tires you run and psi... it's too hard to
generalize without actually riding one, but the 280/320 will definitely
be streetable going by the weight of the car.

 

With the Firmer Setup, I had the Shocks on the soft setting.

 

as you use a softer srping, the normal weight of the car will compress it until the (rate)/(weight)=(compressed length). what this means is no matter how you set the ride height, you will have less compression travel left. Conversely, with a stiffer spring, you have more compression left, but less re-bound. So tuning it for range of travel is an evaluation of the road surface, how hard you are driving it and how much you bottom out or top out. Street requirements are different than the track, where weight transfer cornering or braking does most of the work on the springs.

 

That is one of the nice features of our setup. The Height of the Car can be independent to the position of the spring "Pre-Load" You can adjust the car for more compression for the street, or more rebound for the track.

 

sorry forgot, were those the re-bound adjustables? if so no undulations if on softest setting. (ive been working with simultaneous adjustables..so)

 

my point was the weight will compress the spring a certain amount, regardless of where the shock shaft/body/perch is. compression travel will stop when the coils bind and be determined only by the spring rate, weight and length of spring.

 

Coil bind is an issue that we consider when matching a spring to the shock. We make sure that the coil has enough range of motion to hande the car movement and the travel of the shock.

 

Pilo, anything on this?

 

Off subject a hair...

Yes, and tire compliance is part of the total suspension compliance picture. I was recently informed that 25% of the total compliance comes from tires in a production based car. By contrast, F1 tires contribute 50% of the total compliance. 25% in production cars is equal to +/- 25mm and 50% in F1 is equal to 5mm +/-.

Tires make a big deal.
