Anyone has any suggestions between those 2 brands and models?

And does anyone know if the springs have to be removed in order to adjust the height or if it can be done easily? (I know that H&R's need to have the spring removed on the rear in order to adjust and I do not want that)

Thanks!

 

I recall D2 and Ksport are near identical coilovers with VERY stiff race springs, and dampers that are prone to leak due to the high internal dynamic pressures.

But they may have similar spring mounts in the rear to H&R. They may be more adjustable if they are installed up side down.

Ok thanks. I have verified with the supplier and he said it can be adjusted without removing the spring.

Are there any other brands out there that have a smoother ride? I need a coilover that I can play easiliy with height though. Thanks!

 

So after reading lots of stuff I decided to go with the BC coilovers. I will get them next week. The main reason was because I need to be able to play with the height often without having to spend hours.

Also, as far as camber adjustment it can be done easily from the top of the strut and once I have got the car aligned I can save the position with a mark so I won't have to send the car to alignment everytime I switch from winter and summer heights.

Many brands of coilovers are built that way but unfortunalely not the H&R, otherwise I would have chosen them. After reading many reviews I ended up finding BC is the best buy for my needs in the $1000-$1400 price range.

I will take some photos and give you feedback on the installation when I put them on in a few weeks.

Cheers

 

Not sure why BC told you you can adjust with the spring in because they are exactly the same design as H&R. The collar sit up in the top spring perch and is not accessible when installed. There is no way to make a rear setup for our cars that's any different honestly.

 

I need to see if I can install the perch on the bottom instead of the top. That would make it easier to adjust. The camber adjustment is easier on the BC and can be done in seconds and I will save 2 alignments per year...

 

The bottom perch is shaped like the last coil of the spring and the top is completely flat . If you mount the adjustable collar at the bottom the spring will sit crooked and could shoot out. I'm just trying to be helpful, not derogatory. I tried to reverse mounts H&R for ease of adjustment and it wouldn't work to the point that it would be safe at all. I agree it stinks that there is no camber plates on the H&R coils, that is definitely a nice feature of the BC's.

 

Yes thanks, I understood your reply that way mate I was just checking at the pictures of the rear BC spring set-up and at one end it seemed to have the same diameter at both ends. Maybe I can work something out. I will look into this when I do the install but I won't do something that will work wrong. I'm pretty good at engineering mechanisms but I need to have the parts in hand.

Thanks for your help, I'll post pics of the actual fitment. Makes me laugh when people mention they post a photo of their set-up but all you see is a photo of the car that has been lowered! I mean, wha's the point, they will all look the same once lowered

 

So one end of the BC rear spring if flat wound or ground, and the other end fits in a formed seat? I think BC uses flat wound, machined ends, at both ends. The H&R's you had is as you described.

.

 

Did you check the rates, I think they are almost as stiff as the Ksports. Comfort would be compromised a bit.

Please supply a link to where you found them.

Some owners of Mazdaspeed6 I4-2.3L AWD turbos, made a special order of BC coilovers, where they specified softer rates vs the off the shelf stiff rates. Turned out to be a disaster, as BC just used the same Race struts with little travel. I worked with BC trying to make them work. Would up just using these "specials" on the lighter non-turbo models.

Correct on the BC springs. They have to be shaped like the bottom perch because the perch is part of the A arm and is contoured to fit the spring shape. If BCs last coil is in fact flat it will not seat correctly in the bottom perch. Again, we won't know until you actually get them and see, I'm just speaking from the perch perspective, it isn't flat so the spring almost has to be formed.

 

Selfcorrection ... BC's have 1 flat and 1 formed end, as you noted. There are real race coilovers, where they modify the lower rear arm to receive one of the kazillion different standardized race springs.

I have received the coilovers a couple of weeks ago. They were on back order so it's been a long while since I ordered them now.

I was busy doing the facelift conversion of my 2010 C350 to a 2012 C63. Now that esthetics are all done I will unwrap my BC coilovers

I have found out thet there is NO camber adjustment on my BC coilovers (as they picture on their websites) That sucks big time because it was one of the main reason why I chose BC over the other brands.. I guess i will have to play with the adjustment from the bottom.

 

I've had k sport kontrol pro coilovers on my c230 ... I chose to ride stiff and loved them you can use they key to raise or lower no spring problems.

 

Here we are! I have installed my BC coilovers last week-end. It took me about 5hrs to install them and another 4-5hrs to find the right height and adjust the camber.

For those who might wonder, there is enough stock camber adjustment on the front. I have managed to bring it to spec without any problems. I used a 24inch level on the wheel to find the original camber and I have set the same adjustment to my new set-up. I must have removed the wheels like 100 times (well, at least 5 times) I could have lowered more and still have adjustment left to play with. Also I used a filler gauge between the camber bolt and spindle to be able to set it to the right position at first try on every spring. On the rear I have a little negative camber but I doubt I can do much about it. I was thinking of buying adjustable upper arm but this would push the top of the wheels to the outside and I have no play at all.

My wheels do not rub the fenders under normal driving conditions, even on a rough road but my wife came back with the trunk full of grocery and it rubbed just a bit on the rear at a place that was predictible because of the road condition. I might raise the rear just a little if this happens again.

Positive points: Ride is as smooth as original, Front coilovers can be adjusted for height in 5 minutes each side.

Negative point: Rear camber is not perfect, height adjustment on the rear is a little longer because you need to drop the A-arm in order to have enough room. (no need to remove the coil spring though). That is 3 bolts: the lower shock bolt, the upper sway bar link bolt and the lower spindle bolt which is a pain in the butt to remove in my opinion.

I would recomand the BC coilovers to anyone who is using his car for daily driving and occasional track days. i guess it would be fun to play with the damping in race conditions.

Oh yes end I want to assure everyone, you will see on the photos that my wheel wells are extremely dirty but that is the result of the winter in Canada. Everything is now clean just like brand new

 

Now I understand why people post photos of their cars.. I mean, after all those hours spent on them we have a little pride right? Here is the final look.
Cheers!

 

Look TIGHT !!!! Nice Job !!!! Mind me asking where did you get the exhaust
tips?

 

Thanks mate! I got them off from eBay. The seller is in Hawai. The quality seems really good and the shipping was really fast. They have the AMG logo casted on the top.

 

K-Sport are NOT stiff, with the medium damper setting they are very close to stock. I am very happy with mine.

 

Nice work man! I like the front end and rear! Looks great! Take some pictures whenever you slam it

 

specs on wheels/tires?

 

Tires are 235-35-ZR19 front and 265-30-ZR19 rear. This car is a rear Wheel drive, you could not run this set-up on a 4-matic.


Wheels are 19X9 front and 19X10 rear but I can't remember the offset. I think it was 45 all around.
