Looking for lowering suspensions for 2018 Accord.

Can someone point me to the right direction online?

I’ve looked and none of the big brands have them yet.

D2 Lowering Springs now for sale = Fake News

Been looking daily for something to come out on to lower the car OTHER than coilovers. Tired of paying big money for coilovers to go bad in a year or two and be out that money. Anyways I was just browsing for wheels and seen a thing for suspension and clicked and came across these D2 Lowering springs. 2 inch drop front and rear and says they are vehicle specific for the 2018 Accord. So, who's gonna go first lol

All 3 of those are 9th gen parts. Is the 9th gen suspension the same as the 10th gen's?

My guess is it's another case of vendors making the assumption that they are, just like when the 9th gen first came out and vendors and manufacturers were listing 2008-2012 parts as compatible with 2013+ Accord when they weren't

From experience, BC Racing, Tein, Skunk 2, they all last about the same. The longest being BC which lasted a year and 8 months (all coilovers). Had Skunk2 lowering springs on my 9th gen Si that rode great for 2 years on stock struts for a fraction of what the BC cost for the same vehicle.



I can't imagine that the 9th and 10th are the same. If they wrongly listed these as 10th gen Accord Springs, they could really cause a blunder for someone

For the record...most of the kits out there are actually Civic Springs...it appears that the Civic Springs fit the Accord. HOWEVER, I would suggest against this...might give you the look you're going for, but you're installing springs that are not designed for our cars

Back when I used to own a 2004 Acura TL, the same suspension could also fit 2004-2008 Acura TSX's and 2003-2007 Honda Accords. I ran many different set ups, one being TEIN Springs + Koni SP3 shocks from a 4 cylinder accord.

The springs had a softer spring rate, so the ride wasn't harsh but definitely was more prone to bottoming out if you're not too careful (never had it happen to me). With that said, that was one of my best suspension set ups paired with Koni Shocks because of the slightly softer ride and with a slight rake look.

You're not gonna destroy your car running the civic set up if it fits, but just reiterating what stated, it wasn't particularly designed for our cars so it may ride a bit softer with a slightly lower drop that stated.

D2 coilovers available. Anyone with experience?

Noticed that D2 has coilovers available for the 18 Accord. It looks like the 18 Accord and the Civic Si share the same part number. Anyone have any past experience with D2? How's the quality?

They share the same part number because they fit (bolt up). If I remember correctly, the Civic and Accord now share the same chassis. But just because they "fit" doesn't mean the "tuning" results (spring rate and valving) for their D-HN-25-5-RS coilover they "designed' and "developed" for the 2017-2018 Civic Si will apply to the 10th gen Accord.

If the suspension for the Civic Si (curb weight: 2889 lbs ; weight distribution: 61.4% / 38.6%) will work equally as well for the 10th gen Accord (each trim with a slightly different curb weight and weight distribution), then why does Honda have different spring and shock part numbers for the Civic Si and the various 10th gen Accord trims?

If all you care about is a lowered ride (which seems to be the case for most people) then you'll be fine. But if you care about handling/ride quality too, the spring rate and valving of their coilover "designed" for Civic Si will not translate over and work as well for the 10th gen Accord (IMO) since the Accord is heavier.

Accord Sport
Curb Weight (6MT/10AT) (2.0T)
3298 lbs / 3377 lbs

Weight Distribution (front/rear, 6MT) (2.0T)
60.4% (1991.992 lbs) / 39.6% (1306.008 lbs)

Weight Distribution (front/rear, 10AT) (2.0T)
61.5% (2076.855 lbs) / 38.5% (1300.145 lbs)


Civic Si
Curb Weight
2889 lbs

Weight Distribution (front/rear)
61.4% (1773.846 lbs) / 38.6% (1115.154 lbs)

Thanks for the info. Yeah I agree that it seems like they would have had to make some adjustments for the weight difference. I went back and asked D2 about it... their response was that "there isn't enough difference in weight between the cars to have to develop a coilover specifically for the Accord."
However, they have not confirmed that they will be recommending the same lowering springs in the Accord as they designed for the Civic. ??

I'm going to hold off and see what the other manufacturers release in the coming months.

Eibach Pro Kit expected release early to mid summer 2018

Hi all. Noob 2018 Sport owner here. I just wanted to let anyone know who's looking to lower your Accord.....I spoke with R&D at Eibach last week. They are in the final stages of testing a Pro Kit for our cars. They told me they've been getting tons of calls asking about springs. Provided testing stays on schedule, the springs should be released to market early to mid summer. If demand is high enough, they may release a Sportline spring as well. FYI.

Good information on this thread so far. I've driven a new Civic with these coilovers, and the ride is very good overall. I haven't been in a 2018 Accord with D2 RS Coilovers, but we have sold several sets to customers, and the feedback has been positive so far. There is of course a weight difference in the Civic and Accord like you guys mentioned, but keep in mind on these D2 coilovers you can adjust ride height, spring pre-load, and damper force, which can more than help compensate for that in my opinion.


Keep in mind these coilovers do not fit Touring models.

Here's our product link for anyone interested: https://www.proimporttuners.com/parts/2018-honda/accord-d2-racing-rs-full-coilovers.html

Here's a picture of what you get:
