Are the spring in the front and back different heights. I just my coilovers in today and the back springs were 7kg rather than 8kg and its a different height than the springs up front.

 

That is weird. Maybe they gave you the wrong ones by mistake?

Front and back are the same height. But I think they might have giving you the wrong springs or you might have request for those. But anyway if you did not request for a different springs then it should came with 12/8.

 

OK i contacted Buddy Club USA about it and they told me the spring rate is suppose to be 10K Front and 6K Back (this is because its the U.S. version of the Buddy Clubs). I measured the springs and the Fronts are 7in while the backs are 8in. I'm just going to order some 14k springs for the rear from KingRat and call it a day. This whole time i thought i was saving money i just ended up paying the same price.

 

That sucks. I wonder why they dumbed it down for the US market? Something that expensive should be a "racer" only item anyway... Weird.

Funny, I could have sworn my first set were supposed to be 12F/8KR.

 

Mine are 12/8, says it right on the springs.

 

Are you sure the fronts are 7"? I just measured my 12K fronts and they were 8".

you got one's before Buddy Club USA was around though, right? I think that's a custom rate now..

I think I'd still rather have the ones direct from Japan.. this weird spring rates and length thing makes me paranoid..

If you've got a web link, phone number or other contact info for a stateside representative, please give it up ... I still need to have my old set looket at (or at least one or two of them).

 

The Buddy Clubs with spring rates of 12/8 is for the JDM Spec ones they made a 10/6 USDM Spec one because they think we are a bunch of b*tches or sumthin.

I'll be running the 10k (around 550lbs) springs in the front and a 750lbs (around 14k) springs in the back... a little too stiff for me because i daily drive on it but it's going to be awesome at autox and track events.

D.C. roads here i come

 

Thanks for the info.

Don't worry about them being too stiff (even for DC roads ... then again the roads in DC are barely even to be consider "roads" at times! LOL)

My previous 12KF/14K rear setup on Race Spec BCs was very comfortable (probably more so than my present Lowdowns which are just underdamped/bouncy).

 

I have 10K F/ 7K R. I believe 180 degree turn equals 1k, and 360(one full turn) equals 2k(Buddy Club USA). Anyone have assembling diagram for the upper mounts? I've seen many pictures and they are all assembled a little different when it comes to the upper mounts.

 

They come assembled, and I have no idea what your talking about with "#turns = some K".
Generally spring rate is not determined solely by the number of turns ... how high (number of turns) would 20K springs be and would they even fit the shock being that tall?

I hope Dave and Chad at R&D got me something similar to last time, though it doesn't really matter since I still have the old springs.

 

"I believe 180 degree turn equals 1k, and 360(one full turn) equals 2k(Buddy Club USA)"

My understanding was 1/2 turn(180 degrees turn) of the spring seat would equal to a preload of 1k. I have 10k spring rate in the front, so after the spring has been compressed, every 1/2 turn(180 degree turn) would add a preload of 1k which will equal to 11k. I very well could be confused, this is just the understanding I got after speaking with Buddy Club today. This is why i started the staement with "I believe". correct me if i'm wrong.

 

oh yeah, mine came with the upper mounts not installed.

Are you reffering to the pillow-ball mounts?

 

I am kinda new to this but, please don't flame me...was just wondering why you guys put higher spring rates in the back than front for track use?? can somebody explain this to me?? i know that when you put a stiffer anti-roll bar in the back you get a better turn in...so what does higher spring rates in the back do for Road Racing??

 

ive ordered a few sets of buddy clubs... came all JDM'd out, 12k 8k fully assembled. I guess they have changed the versions around now.

I'd like to learn more about preload on the buddy clubs

anyone care to explain further?

In a like-for-like comparison, it generally will permit the car to rotate more thus decreasing our FWD tendancy to understeer/push. I run 14k/16k for this reason, but I know many others that run a much more extreme setup than I. I tried an 8k/14k setup and it was WAY too loose for my taste. I generally like to see where I'm going through a turn, not looking at the particular corner worker at the apex like some do

A lot of other factors come into play here, too. Tire pressures, sway bars, etc can all have a significant effect on this.

 

Nice...i got an basic understanding now...just starting to get into suspension tech know...

Thanks for your answer

Spring rate stays constant. 10k=10k doesn't matter how much you preload them.

edit: expect for progressive springs
