Wonder what if any are the long term ramifications are of doing that.

If one is lucky, the cheapest ramification will be premature replacement of the OEM shocks and struts. A more worse case ramification, will include premature wear of additional suspension components.

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)

D2 Springs on mine with 20x8.5 and +30 offset. No rubbing BUT they are basically kissing the lip that sticks out towards the tire on the inner fender. Gonna have them rolled, then there wont be ANY worries.

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.

Just springs alone?

Yep, nothing else available as of yet unless you wanna pay $1150 for a custom set of coilovers. And update, with my offset and wider tires it now rubs slightly on turns now that it has settled. So I turn easy and slow. Still trying to find someone to roll fenders.....living in the middle of nothing sucks.

Axion Industries now has the Eibach Sportline Springs on sale on their website as of today. If anyone wants to lower their car with spring for our actual cars, here's your chance.

Nope.

Just like with https://www.driveaccord.net/forums/...et/forums/257-wheels-suspension-brakes/505202-d2-lowering-springs-now-sale.html

You really should verify with the manufacturer before rushing to post that something designed for the 10G Accord is now available when it's not designed for the 10G Accord.

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.

So Eibach are actually developing and testing springs specifically designed for the 10G Accord vs reusing the Civic springs and saying "Eh, good enough" like D2?

Example of the difference between a good suspension company and a shitty one.

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:

These coilovers seem to be very affordable. Eibach lowering springs + camber kit come out almost as much as a full set of D2 coilovers. Have any other manufacturers announced coilovers for the Accord for comparison?
