Thoughts on the Dinan Performance Springs

col4bin · 10-12-2015, 12:40 PM

I would like to lower my M235 just a enough to get rid of the gap in the wheel well. Does anyone that has these care to comment?

Thinking Dinan as I want to keep my warranty intact.

I might do the springs on my 228i, although inevitably the labor will be expensive. Two pieces of advice, FWTW: (i) you will be better off doing this through a specialist tuner shop with a well-established Dinan license rather than a dealership, even one authorized to install Dinan products. There was a horror story in these forums recently from a guy whose car was all but ruined when a non-Dinan BMW dealership (also his employer, ouch) installed his springs upside-down. He was $1000 down with a crippled car and no warranty on the work. Always use a high-quality Dinan performance shop. Finally, (ii) make sure you get the ride kit with the springs. Good luck and please keep us posted.

I had the springs installed on my m235i about 2 months ago.. I definitely recommend the upgrade. I have been using the same high quality shop since I first got my license, (I'm 35 now) so I trusted them to install them properly. In my opinion, this is the way the car should've came. It handles better, the gap is closed giving it a nice even look front to back, recovers from bumps faster, rolls less, and in sport mode isn't harsh at all. To me, it feels just right. Hope this helps.

Thanks. Anyone have a good rec in the San Diego area?

Could you post any side shots of your car with those springs installed? Thanks.

Steve80bk · 10-13-2015, 01:00 PM

Here's a few shots of the side.

got the springs and supplemental kit. pleased with the drop height and ride. Improved ride with better handling. When i say improved, i mean no more crazy bumpy ride, less roll. seems like dampening is a lot better. No issues with clearing speed bumps or driveways...

Really like the conservative drop of Dinan springs. Has anyone paired them with aftermarket shocks?

Michall · 10-16-2015, 10:00 AM

To those who installed Dinan springs. Do those springs come with the hardware or you reused the old, stock hardware?

MrBimmerM235i · 10-16-2015, 01:58 PM

Dinan drop with spacers...

Ace604 · 10-19-2015, 06:40 PM

How much lower are the dinan springs compared to the m sport suspension?

The M Sport suspension drops both axles 10mm. The Dinan springs drop the front axle 1/2 inch (13mm) and the rear a full inch (25mm). Simple math says the Dinan springs will drop a car with M Sport suspension 3mm in the front and 15mm in the rear.

Here is mine on the Dinan Springs...do not bother with those overpriced E30 M3 bumpstops (which you can just get at a dealership) that Dinan calls a supplemental comfort kit. Just cut your stock ones (no shock disassembly needed) takes 5 min each side and you get the same smooth ride. cheers.

Then do you need to get new bump stops when going back to stock if you cut them?

No, it will not effect the ride quality when you go back to stock.

I wonder if the same could be done for H&R springs...

Yes. I will bet after 10K+ the car will get bouncy...at least that has happened with me on every H&R spring-only setup I've had unless I cut or got shorter bump stops. There simply isn't enough shock movement over time and the shock will surely lose its rebound effectiveness. good luck!

MrBIMMERM235i...I have the front splitter too, did you have problem clearing road bumps after installing the Dinan spring & handling kit?

M235iCA-guy · 10-28-2015, 03:29 PM

S1UMA1...what wheels and setup do you on your car?
