i drive my car on the street, thats a $5k setup with springs or just the struts for $3k without springs. Overkill for me.

You say this, but the MCS dampers can provide a more supple and smooth ride over stock, with less NVH (damper to damper)

Are there any other alternatives for about $2.5-3k that would include everything?

everyone's own taste but to me a proper suspension no matter street or track is super fun, watch the video where he bangs through corners. again for my own taste i like coilovers where you can set low/high speed compression for getting the maximum benefit from coilovers. so my recommendation would be kw cs 4 - 3 way or nitron r3 or something in this class.(the cars in the video uses these if I am not mistaken) stiffer low speed and medium high speed compression will probably feel better than stock for many people but depends how sensitive you are.

Apart from that kw v3 or kw ddc are options but i wonder how much difference these will provide to solve your problems straight away.

I would personally just get a set of MCS 1 way non remotes, coilover rear as well…you'll save cost not having to get height adjusters, and you can also run a lighter rear spring rate. If cost is an issue, maybe you can snag a 5-15% discount on Black Friday w/ Bimmerworld. Just order the dampers themselves, then wait a month or two to build more funds for the remaining parts.

The car's on-track behavior with a good damper like this is just an amazing thing to experience. Pro tip, you can run the rear coilover's adjuster on the bottom and nothing will rub when you combine with the Bimmerworld-H&R sway bars

How long do these coil-overs hold up on the street before needing to be rebuilt? It might be a good idea to do next in terms of mods. Especially if it can hold flat in corners but absord sharp little bumps from poor roads.

On this topic, since I'll likely be in market for a suspension upgrade when I get my car back (hopefully)... so to run the inverted coilover rear, one needs an upgraded bar to avoid rubbing? I know there were some threads on this somewhere regarding interference with the endlink, I seem to remember talk of using a spacer/shim to get things to work with the stock bar. Swapping out the rear bar is a big PITA so would be nice not to have to do that. Thanks

Agree. However, for the vast majority a good 2WR system is perfectly suitable/capable for the track. A 3 or 4 way is probably overkill to start out.

I think Colin Chapman (the Lotus guy) is famous for saying that if you make the suspension adjustable they will adjust it wrong.

This thought didn't escape me when I saw the features on the recently launched 992 GT3 RS. Maybe I'm just too old and cynical to appreciate that fancy tech.

That's not a bad price for a quality suspension. You should see how much Penske suspensions cost.

Don't make the mistake I did and cheap out on suspension mods - it'll ruin your experience with the car and you'll regret it later when you're inevitably disappointed. You don't have to go max stiffness race suspension. The MCS single adjustable option seems like it would satisfy your needs but again, I can't speak from experience - I only share because of feedback from very credible folks including the guys on the track forum here.

this is it. I did the same mistake over and over again and end up getting every type of suspension/coils/shocks/springs. Every single time I purchased something cheap I thought I got it. huge mistake. everything started "I want the car to sit a little lower" 200$ eibachs which is a huge insult to the car in my opinion.

The reason i offered 4 way over 2-3 way because you stilll have to compromise something. Also camber/caster adjustment is a big plus. But if it is going to be your first coil set it might be hardcore so you actually better start with something cheap and see what you can achieve with proper suspension. buy used stuff, no need to get new for a 8 year platform

these needs to be rebuilt in every 12-15k miles as far as I remember and a.

Tractive suspension + OS Giken differential 💪🏼

Good question. Also curious, waiting for someone to respond

Will be perfect on 11

I have Apex sm10 10"&11" wide, et 25F & 44R plus 12mmF spacers & 7.5mmR spacers

Here is a pic of my car with the 285zp F and 305(98y) R

Thank you. Appreciate your suggestions about the tires. I wouldn't have known.

Skiy what offset you have on rear wheels?

In the pictures on the first page the 285 tyre seems to be at the limit, and in this last photo with 315 it seems that you can still use a wider tire

I never had the 285 on the rear. Its a 285 in front but it runs wide. Thread width is 11.2" on my 285 and stock cup 2 in 305 has a 11" thread width

I had the 305 regular cup 2 in the rear and a spacer. 12mm and then 10mm. Currently on 315 there is no spacer so yea there is some room left.

Rear ET?
I like the look with the 315

19x11 et43 2.2* camber. Will reduce camber to 1.8 and then see if it needs a spacer to be flush

Hi David. Can you take a look at these photos and let me know if these lines on my thread look normal or what is it from. Its not corded and same on both sides. These are the c7 vette cup2 front tires.

Could this be from driving in really cold weather?
