H&R springs... M5 or M550i?

clutchdj · 05-20-2019, 11:00 PM

Hey guys, F90 non comp on stock 19" pirelli's

I have noticed the stock rebound dampening in the rear is aggressive without being bouncy; looking to soften things up for road trips tbh. I like I slight fwd rake that the F90 H&R's display above.. sort of like splitting hairs as they both look awesome

Can anyone comment on which spring set (m550 H&R or F90 H&R) offer a more compliant ride. TIA

I have 21" rims on mine will the 550 springs work with that or should I do KW HAS???

Usually, lowering spring will not soften up your ride.
My suggestion is to play with tire pressure before looking into lowering spring.

21" will work with M550iX spring, just depending on how is your 21" setup.
But, if you are not sure about how low that you want to go, KW HAS will give you a range of drop that you can play around with to your liking.

I run 28psi cold all round. I am beginning to think it’s the brick

hard pirelli sidewalls that I’ve experienced in the past. I have KW coil overs w/Michelin’s on my F80 and the ride is less harsh. Do you sell springs. Which H&R is more compliant?

Have you check that the delivery block in the shock has been removed?

Spring wise between M550iX and M5 should be similar.
I've rode in Vic55 with H&R M5 spring and my local customer's with KW HAS. None on the M550iX H&R spring on F90 M5 yet.
I am fine with either of them, no complaint at all.

So, my guess, the M550iX spring on F90 M5 should be good also.

clutchdj · 06-13-2019, 12:53 PM

it was the harsh 19" Pirelli tires as I had suspected. Even at 28PSI cold, the side walls did not compress which was actually amazing. Put on stock 20"s w/MP4s and the ride's less jarring. I did check for suspension blocks - did not find any :-)

M550

clutchdj · 06-18-2019, 02:22 PM

How's the suspension compliance around the boroughs with the springs. Looks nice.

Not gonna lie on NYC roads it's harsher but whenever I go upstate you can feel the difference. #NYCRoadsSuck

FloridaM5 · 06-30-2019, 06:09 PM

I do like the way they look on members' cars. Haven't installed on mine yet. Was waiting until after 1200 mile service. Seeing the dinan kit, which looks quite nice and effective, may head in that direction.

I've rode in Vic55 with H&R M5 spring and my local customer's with KW HAS. None on the M550iX H&R spring on F90 M5 yet.
I am fine with either of them, no complaint at all.

So, my guess, the M550iX spring on F90 M5 should be good also.

Hello,- i have 19 M5 Competition. Currently on 20" looking lower car. I know the M5C sits a bit lower than the regular M5. Any suggestions on H&R Springs - M5 F90 or M550i. Looking to lower to fill in gap

So I had 20 inch Titans before 21 inch BBS so u can see both in these pics. I'm on H&R m550i springs. Thx

Hello,

I have a ‘19 M5C and looking to lower it, however, just the front. I’m happy with the way the rear is set up, but I’m planning to put a 10mm spacer and dropping it on H&R springs. Curious to see if anyone here has a similar set up and how does the car run afterwards? Is there a possibility of issues with the fronts having spacers and different springs to the rear?

I wanted to something similar but was advised against it as spring tolerance in front versus rear will be different and wouldn't work with the car and may cause ride issues. Thx
