Tractive Plug&Play suspension installed (with EDC)

Gah, I really want these...

Absolutely perfect

Anyone else upgrade to Tractive suspension?

I have these shocks and the DSC Sport controller on my C7 Z06 and they really are phenomenal. The car rides better than stock in tour mode and I've dropped 2 seconds a lap at VIR with them. I can hammer the curbs on track all day long and it never upsets the car. The softness in the stock suspension that had me dragging the splitter under braking and rubbing the wheel wells in cornering is also gone.

I'm going to keep bugging DSC Sport to adapt their setup for the F8x. I think they just have their hands full right now ramping up the Cayman and Corvette stuff. Hopefully we can get this on their roadmap.

Winter setup.

Please keep me in the loop if possible - I'm local and interested. I do all the suspension work at RRT in Dulles, they are a very competent BMW shop.

I can't believe how poor of a job BMW did on the M for rebound body/chassis control. It's so sloppy and unconfident inspiring

Concur. Drove my friend's Cayman GT4 and 911 GT3 and found the damping quality mind blowing. It was their best attribute in my nonprofessional evaluation.

Yeah, Porsche has suspension and braking down pat.

Every road/track test I've ever seen on any modern Porsche, the two things it's ALWAYS praised for is it's braking and suspension damping.

I'm sure I'll get some hate for this, but I don't think M division is putting out what they are capable of. They have clearly fallen behind on most performance matrix attributes.

I think ///M does well on everything except suspension and traction control settings. Americans are miles ahead in these two areas.

[Mjaspreet]

Can you go lower or is that the lowest you can go?

Im not from America. But i dont have the feeling that american cars are miles ahead at suspension.
See where all big suspension manufactures(cars/motorcycle) are coming from :
Ohlins, KW,Bilstein, WP, intrax, AST, Moton ,koni, proflex nitron, k-tech tractive Eibach , H&R

Point taken. Still I'm curious who manufactures the magneto rheological dampers found in some of the better American sports cars of the moment.

I know it is also used in Audis and Ferraris but not sure who makes it.


But as a counterpoint, I'll ask you why doesn't BMW use the topmost quality dampers in their flagship sport sedan? It is of noticeably lower quality than some of the competition's.

Think M makes too much comprimises. Its a sedan/coupe not a 2 seat sportscar. They want it to be good for the dailydriver and for the track, but thats not possible. its a comprimise

For Porsche 2 seaters its easier , less comprimises. no 2 persons in the back, less- to almost no luggage space ..... Its the same with sport motorcycles always too soft , made for passenger

my last car was a 997 GT3 , i had to replace the original suspension because already at 50k kilometers. it was squaking all the time. Even Porsche wanted to give me 50 % discount on oem , but i didnt want their suspension. I went with Intrax ( its a local company) suspension was much better. Higher quality and serviceable. The oem is not.

I'm waiting for my m4 lci. So I dont know yet how good/bad the suspension is. But if it is bad as i read here sometimes i will upgrade.
I will go with intrax (have experience with m4 racing) or tractive ( that company is also local , 30 km drive)

Dont know who's making the magneto suspension. but that one depends a lot on software

It was desigined and made by Delphi which is a UK company but the division has now been sold to a Chinese manufacturer.

Your LCI will be mostly fine. It's the rebound IMO that is too hard, which coupled with the solid mounted rear subframe can cause the car to skip around a bit, and generally not give you that "one dip and done" feeling.

Hey mate,

I noticed you said that the car rides more comfortable in comfort mode with this suspension setup than the standard springs and shocks whilst gaining traction and stability? Normally when you lower a car it rides harsher than standard?

Just curious to know how the comfort is in comfort mode with the lowering springs?

Do you know what pricing is for this setup?

This is the lowest setting.

Yes yje car still feels more comfortable even the damphers work miles better. And the car feel much more stable and nimble. I remmember the stock set up as a bad dream for this car, it should has this damphers and springs from the factory.
In sports plus it is harsh but still you can feel that damphers works much better espessially when you attack the edge on track. That keeps car more stabel and gives more grip.
I'm totally happy with this set up even thinking in getting ZCP sway bars or not.
Also I'm thinking in getting the GTS ecu map because the car is ready to put more power to the ground.

Sounds like the real deal this suspension!! Do you need to re-mortgage the house to buy a set though? Any idea on pricing?
