At risk of sounding like a d*ck, how about you share your skills/experience with us first? How many events have you done, how familiar are you with chassis dynamics, spring rates, damper rates, and the effect of each on the car's handling?

I mean, you can go to 5,000 way adjustible Motons with 1,000 lbs springs and infinitely adjustable swaybars the sizes of Ahrnold's biceps, but if most of your "car set-up" knowledge comes from playing Gran Turismo, you might be better off with a set of matched springs to dampers, especially for a daily driven car that sees track time occasionally.

Ok well you did sound like a d*ck, but it seems you mean no harm so ill go at it.....

This is actually for my cousin who is not a member on this forum but lives 10 minutes away from me and we are both car ppl anyway let me cut to it, he hasnt been on the track but is a talented driver he does stupid things on the streets someone should probably kill him for so im sure hell get in the swing of the track in a considerably fast time, Hes a highschool kid such as I, but he wants coilovers over shocks/springs obviously - and I had originally thought bilsteins were some of the best for m3's and then I saw the group buy and suggested those possibly and he said no Kw's are the best, so I wanted to know Which is the best car for harshly aggressive driving on the streets, and does not have to be the champion of the track but it can definetely hold its ground.

Now were not looking for anything crazy such as 2-9 way adjustables, just your basic nice set of coilovers not over $3k.




EDIT: NO NOTHING ABOUT DAMPERS AND ALL THAT SPRING RATE TALK LOL

Where do i go to learn these things?

By going to the track and learning what your car is missing. It will take a while before you can even come CLOSE to driving at the limits of the car. There's no point in upgrading until you understand why you need the upgrades and you can pin-point which upgrades will create the changes the car needs. You're taking the wrong approach to throw parts at a car before you even know if the car needs to be upgraded.

How 'bout just not driving like a d*ck on the street? High school kid in an E46 M3, sheesh. I'm not exactly old (27), but I remember how dumb I was at 17 and if I had an E46 M3 then I'd be dead now.

Leave the car stock. Go to the track. Listen, listen, listen. Drive, drive, drive. That will make your car much faster than any suspension you throw at it now. The nice part is, it will make your car much safer too. The really nice part is, it's cheaper--and the BEST part is, it will make every car you ever own faster and safer. The looseness of the nut behind the wheel matters a lot.

Oh, and us old folks have learned that it's perfectly acceptable to write out whole words on the Internet. Give it a try, you might like it.

BlueBullet328, do not listen to these club racers and hpde wankers. I am professional racing driver who is very active in the KTCC, but a few years ago I was in the same situation as you. I did not know very much about suspension, but once you start shelling out some money for private suspension geometry classes, it really gets you educated.

That being said, let's cut to the chase. I recommend that you contact JIC Magic USA, as they are the world's first and foremost in suspension technology. There's actually a perfect setup for you that JIC offers: it was originally developed for dan dan kokoro pass racing in Japan, otherwise known as touge. It's actually been featured on Best Motoring on the Gunsai segment.

Contact Jon over at JIC Magic USA, and he will hook you up with that kit, it's called the TG Street/Track Kit, and they only sell it to people who contact them first. Tell him "Junpei" told you about it. It's only about $3,001, but WELL worth it. Trust me, you cannot go wrong with it.

For spring rates, I recommend that you run around 890F and about 3483 in the rear. This will give you that just freshly paced railroad track gripping feeling. Don't set your dampers to max though, as that will not be super comfortable, although I drove in Alaska on some crappy roads with full stiff, and it still rode better than stock.

Hope this helps, don't let these pruneys bother you. PM me, if you have any more questions.

Happy Motoring!

I you really want a coilover setup I'd stick with something off the shelf. Bilstein PSS9 will do fine.

There is not a really big difference between KW var 3 and PSS9 for that matter. Springrates are roughly the same as well as damping adjustments, both can adjust compression and rebound without too much complication, adjusted with 1 knob that simply turns them stiffer or softer. Just follow their setup advice on what heights to set initially and you should come a long way.

The BEST would be Ohlins TTX46/TTX40, or Sachs/Moton/Penske 4way.

Sounds like you just need a basic setup, with proper spring rates and setup.

We've got AST single adjustable coilovers in stock that should work on your cousin's E46, but they are not the cheapest solution he will find, either. These are monotube adjustables similar in design to Ohlins, Moton, etc, but valved for a dual purpose car. We can do spring rates from "mild to wild".

Drop us a PM for more. We can make 4200 double and 4300 triple adjustables as well for the E46, but costs do go up accordingly. For a dual purpose street/track car, 4100s tend to be a great solution.

Bro just cut your springs, that will increase the rate of all the springs by 400LBS and will make the M3 handle like it's on RAIIIIILSSSSSSSSSSSSSSSSSSSSSSS.


Just stick with the stock suspension. BMW wouldn't call it an M3, make it THE benchmark sports car, and give it horrible suspension/brake components..think of that. No need to upgrade ANYTHING until you've reached or know well aware the actual capabilties of the car.

10-23-2007, 04:44 AM
Go to a few track sessions, learn a little, and then get an aftermarket suspension.

If you have your panties in such a bunch, either go with TC Kline, Ground Control or Bilstein PSS9's. You won't notice the different between any of those.

Don Nguyen
10-23-2007, 12:26 PM
Well lets hear some input compared to some Kw's or GC's

From my experience and knowledge, I rate it like this JIC > KW > GC.

The material that JIC uses for their suspension is top notch. Unlike the metals that are used in KW/GC, the JIC material does not degrade or wear out over time as quickly/easily.

The main difference that I have seen between JIC and KW and GC is that GC uses linear spring rates, vs the progressive springs that JIC and KW uses.

The design of the front shocks on the JIC coilovers is something totally different, and better, than what KW and GC offers. They have a reversed tube, allowing you to effectively lower your car, but at the same time, maintain a good amount of shock travel.

Also, JIC uses reinforced strut pistons. Basically, it is designed so that it will be very resistent to bending under extreme loads. They have this design, all around, for rally cars like Subbie, etc. The whole piston is basically the size of the entire shock tube.

JIC has a lot to offer. If I had to, and I probably will, I would get/switch over to JIC. I currently run GC on two of my M3s, and I am not entirely happy with them, same with the H&Rs on my 911. I may be swapping all of my cars over to JIC.

I sell both JIC and KW, and have tried selling GC (and run on two of my cars) in the past. It isn't like I am trying to sell JIC, just because I carry it, but because I believe that they are the best for what they are.

Don Nguyen
10-23-2007, 12:31 PM
Like others have said as well, it is probably best for you to just take your car out as is. Then change/upgrade parts as you feel the need too, once you have maxed out its capabilities.

However, if you want your car to look cool, and get some benefits from a coiover set up as well, then don't let anyone stop you from doing that.

It all depends on how you want to take the approach. As much as you may not like it, I would also take the advice and listen to what a lot of people have to say on here, as they know what they are talking about.
