which lowering spring give you the most drop

[BillNguyen]

What spring give you the most front drop. Here is my issue I’m currently on eibach v1 spring they feel great handle well but my issue is that the drop in the rear is perfect about 0.5 fingers wheel gap but the front is about tight 1.5 finger wheel gap or about a 2 cm difference from the rear. So what spring kit do you guys suggest for the f83 so give it even wheel gap or mix and match spring.

Why not go with KW HAS?

Is there any other option because my eibach from the web say lower the front by 0.8” and the kw say from 0.2 to 1” so it only a about 0.2 inch of 0.5 cm difference which I can’t justify the 1.5 k price

If you’re already on an Eibach set and go lower you risk blowing your dampers. You’ve already reduced your ride height and the dampers ride more compressed than normal. This reduces their window of action and has you hitting the bump stops more frequently. Since the front dampers get more work they need that extra bit of travel.

[BillNguyen]

I also hear that h&r ss spring can give you as much as a 1.6” drop but that for the f82 so does that matter for f83 and do you know of anyone that has suspension damage from running those

[BillNguyen]

Here is the difference the front and Rear

[therealkenc]

It would’ve been almost perfect if you had just switched the front springs to Eibach V1s and left the stock ones in the rear. Lots of folks do this to prevent a negative rake.

Without trying to be an asshole about it, you are aware of how suspension geometry works right? TopJimmy did just explain briefly the additional work your dampers will have to do with the less travel it has due to the springs so it isn’t a matter of knowing anyone when with the proposed lower drop you seek you’d become the one in that situation that he advises against.

As I commonly like to say in these threads, I will never understand the purpose of HAS kits when it’s about compression and rebound. I stress that fact because folks will just throw lowering springs on and say the car handles better, if you’re going to touch the suspension my 2. cents is do it right the first time and go coil overs as many of us here have and for good reason.

Do you have any recommend for affordable coil over that are comfortable not too stiff because this car is a convertible so it not going to be setting any hot lap time also would be nice if I can retain the edc

Just cut your front springs and be done with it.

MP or KW-HAS can be found somewhat economically here on the boards.

I installed the BMW MPerformance Coilover conversion kit and do like it. It’s not a full blown Kw coilover system but keeps stock EDC and ride is good. It lowered the car about an inch and I may raise it up a bit to minimized banging the nose of approaches. It’s not going to give a full stiff cornering ride but gives you some adjustability and close to OEM ride.

My car is mostly street with a BM3 Stage II tune with some autocross. If I wanted to track it a bunch, then I’d get another set up. If you use this system and do a DIY install, use a press for the front spring perches and don’t do the YouTube hammer trick on a $1.200 strut…..

Price shipped from a BMW dealer was $1,150 and full retail is around 1,500. Four hours to install in my garage using Quick Jacks.

When my shop aligned it the camber was pretty aggressive around -1.9 degrees at the front and -1.8 at the rears.

[BillNguyen]

Also do you guy think an alignment is necessary after any spring install here is another problem I come across on the highway I do usually go on high way for a very long time but 2 days ago I had a 200km road trip and I realized I have a lot of vibrations at about 120-140kph I read on some forums about this and someone suggested that teflon tape would fix the issue by applying it on both hub ring and it did fix 90 percent of the vibration there is still some could getting an alignment fit this?

Highly recommended to do an alignment after lowering a vehicle. You are altering suspension geometry so you need to know if you introduced any potential issues. As for vibrations, depends on the vibration. Have you tried getting your wheels balanced? Are you on aftermarket wheels that might be missing the plastic hubcentric centering rings? There should not be any play between the hub and your wheels that would necessitate Teflon tape. Unless of course you have spacers. This hack fix is used with poorly machined spacers to eliminate play.

[BillNguyen]

I have had my wheel balanced for about 1 year now but from what I can tell before lowering spring there was 0 vibrations I guess I’ll take it to an alignment shop tomorrow to get an alignment and hope that solve the problem

My m&s springs gave me a stupidly low drop, and i scrape on speed bumps and driveways all the time. Handles great, but can be nerve wracking.

Does the HAS kit not overload the shocks if you lower them too much?

All dampers would overload of run too low…that applies to HAS, coilovers or just lowering springs.

I know OEM is gonna be the best as far as not wearing out the shocks prematurely but is there a lowering spring that's considered "safe" when it comes to lowering springs while still getting some decent drop? Thanks.

I’m not the pro on recommending suspension. Best to get others’ input here.

I'm on H&R springs and my tires are almost tucking.

My car is like that but I’m trying to get the front to be lower because I’m trying to get the rev rake look
