Thread: B13, B14, B15 Suspension Information...

Link fixed.

I did read it, I just didn't comprehend it the way it was intended
I read it all over again, think I have a better Idea.
so the problem that we face is if the tire/wheel combo offset is too high it will rub against the strut/sleeve but cant that be compensated with a lower off set wheel ? lower than stock of course

I'll ask this in the suspension thread

Heres one question, where can you even find koni inserts anymore? Spec V or B13? Ive searched tire rack and even the evilBay with little luck.

Spec V from Greg V at G-Spec (Forum Vendor).

You cannot get the B13 Koni Reds for the rear anymore, discontinued. However, you do not shorten the rears anyways. So you could run AGX in the rear with B15 Yellows in the front.

Here's more discussion:

i got the last one.. I had bought a single from panx2kser and when i called Koni, they had just one left.. I am guessing that when Matt O. bought his single for test fitment purposes, that he through their whole supply into an "odd" number and then I bought the last one to make it "right"..

seeing as most tracks are free of potholes, I would say it matters more for daily driving..

Ahem....I have one full set of Koni B13 Red rears being made into CSK's for me right now by Will, with B15 Yellows up front.

I also have a spare set of Koni B13 Red rears BNIB sitting in my Tahoe.

unless the Koni rep lied to me, you must have bought them before I bought this one.. . He said it was the last one on their shelf and that they were discontinued... not that it really matters.

now I have a set of blown B13 reds for all four corners that I'm going to send to Koni to have revalved and made externally adjustable with a custom rebound/compression.

Something slightly stiffer than B13 reds ...

B13 red REAR insert:
min rebound: 500 newton meters @ 13" per second
max rebound: 1000 newton meters @ 13" per second
compression: 300 newton meters @ 13" per second

B13 red FRONT insert:
min rebound: xxxx newton meters @ 13" per second
max rebound xxxx newton meters @ 13" per second
compression: xxx newton meters @ 13" per second

I need to call the Koni rep back up and ask what the B13 red FRONT insert is from the factory...

B15 yellow FRONT insert:
min rebound: 1050 newton meters @ 13" per second
max rebound 2100 newton meters @ 13" per second
compression: 450 newton meters @ 13" per second

Upon looking through the suggestions for the GC + CSK coilover setup, it came to me, what would be considered a good coil spring? That is, rather than the provided Eibach springs that the GC's come with, is there any suggestion of a better alternative coil spring?
