The car is a little SWIFTer now
If you have seen my other threads then you would have seen my Hotchkis sway bar install and that I am in pursuit of an even better handling e36.
I am currently on TEIN SS-P's and I love them. Now they aren't AST 4200's or TC Kline D/A's but they have been a great coilover to date. One thing that had bothered me though was the spring rates. I am currently running 559F/532R. For a car that is only 3150lbs, 550+ is a pretty aggressive rate for a car that is 95% street driven. So, I started talking to my local shop, HP Autowerks to see what they suggested to increase handling and comfort (I realize this may sound like an oxy moron). Harold, the owner, suggested that I change my spring rates and at the same time step up to a much better quality spring in the process. Also, he suggested running a linear spring rate in the rear for more consistent handling. So, I went ahead and did it. I chose to go with Swift springs as they have had terrific reviews in comparison to Vogtland and Hyperco (both respected brands but Swift outshined them in testing). Basically, what is to follow is the first TEIN SS-P Swift Spring conversion. Description of picture is below picture. Everything at the start. Swift 448F/616R Springs, Swift Thrust Sheets, AST Rear Height Adjusters and Vorshlag Nylon Seats. Swift Front Springs Thrust Sheets (Help to keep the spring free moving/prevent twisting which results in spring rate increases) 6" 11 Kilo 60mm Spring, quite light 6" 8 Kilo 65mm spring Front Spring Tein weight 559LB 65mm 7" Vogtland Weight 450Lb (8 Kilo) 60mm 6" Rear Spring Weight TEIN, Progressive Assembled Assembled rear spring weight Tein Assembled rear spring wieght AST Rears Before Comparison pic |

Rear After Front before Fronts assembled Very nicely designed camber plates. Monoball Fronts installed This change was definitely worth the cost of admission. It was a good way to upgrade and it didn't hurt that they are some of the best if not THE best springs on the market right now. I did a lot of research and this mod was actually spurred by all the recent testing that has been done by a member on e46fanatics.com. I know it isn't a direct comparison because I switched up spring rates but the higher spring rate in the rear feels amazingly better and smoother than the TEIN. I really hated the way my car used to act going into the corners and how high my front spring rates were (it probably decreased traction) but now the springs suck up the bumps in the road. It feels much more athletic and responsive which is what the advantage is supposed to be of a light spring, a quick reaction time. The member on E46 actually put the car on a shaker to measure response plus these spring don't sag like the Vogtlands and are worlds better than Eibach's offering. This is a great upgrade for all you KW owners as well since your whole system is progressive and has poor spring rates in my opinion and many others. Special thanks to Leonard at SWIFT for answering my questions and HP Autowerks for getting everything sqaured around for me. For those of you may think that I am talking out of my, you know. Here is some data that helped me make my decision. Quote:

that's a good write up.
linear springs in the rear huh. Swift 448F/616R Springs i'm just trying to find a good excuse to try the swift springs - the linear springs specifically. i didn't even know it was possible with Teins - now i know u can. awesome. it'll be something to look into after I add swaybars.

Very, very good writeup! I love all the pics!
Makes my decision for upgrading my suspension a little more tricky, especially with all the different options there are out there!!

Thanks! It always frustrates me when people do write ups but always leave you guessing at what they really did. As the saying goes, a picture is worth a thousand words so I guess I'm up in the 20k in this thread.

good work Harold. Quote:
OBI or OBII. I so want to try the swift springs, Harold knows - I hit him up a few weeks back for the Koni SA. I'm rock'n some Tein SS-P right now. So your review helps out.

those wheels look pretty sick, but they look heavy. What do they weigh? A lighter wheel can make a huge differance. I saved ten pounds per corner upgrading to Breyton GTS R 18" from my stock 18" sport wheels.
The write-up is awesome. i plan to call harold soon so he can help me burn some cash I will be getting soon! |
