Great tire choice!
We are big fans of Continental tires, light weight, high grip, and great ride quality too. With these wheels and tires coming in 5 pounds lower than stock 18x8 combo the ride feels nonetheless the same...which is pretty amazing given we are about half an inch more width for rim and tire and jumped from 18 inch combo with taller sidewall to 20 inch combo. No regrets...and I love the look.

With the brake upgrade the plan is to further improve ride quality with another big reduction in unsprung weight (factory calipers are very heavy cast iron lumps) while we also massively improve brake modulation with a modern 6 piston caliper.

This is the setup on wheels and tires, I was considering, but have been told ride quality suffered horribly. Is this a true statement or not? Please let me know if there is a rubbing issue and anything like that? Also, does the truck feel more stiffer with your ride quality? Thanks much on your feedback.

Ride seems good as stock so far, including over the railroad tracks we have next to our shop, so I doubt that other guy had the same setup (particularly since this version of the tire is brand new, 'EXTREMECONTACT DWS 06 PLUS'). I have the tire pressure a little high right now rather than per the door frame factory recommendation, when I lower it to factory it will be smidge nicer still. And this wheel is also pretty much brand new, Enkei XM-6 20x8.5. No rub found thus far.

I too am running the same wheels and tires on my 2017. I lowered mine 2". Rides great!

Love that look on the white Ridgeline!

Lowering ours 2 inches soon too. Thanks for posting the pics, gives me better idea of how ours will soon look with the same wheels. And our 6 piston calipers going on the front are RED, so the fact you painted yours gives me some idea how that will look too.

Who told you that? Does this person own the Conti DWS? Mine have been great
It's not so much about the specific tire as the tire size. Less sidewall = less cushion, in general. Whether or not you can actually feel a difference is largely up to suspension tuning. 17s vs 20s on an otherwise stock VW GTI is very noticeable. The 20s have crisper turn-in at corners, but noticeably rougher ride over washboard-y pavement. No idea about the Ridgeline, as I haven't swapped wheels/tires.

And yet there is a lot more to it than just the sidewall profile, which is why we picked that Continental in particular, and wheels that combined with the lighter tires drop unsprung weight by 5 pounds per corner. Such a big drop in unsprung weight can and often does counter what otherwise would be the impact of shorter sidewalls. Here it seems to be about a push from my time behind the wheel so far, the sidewalls are shorter but the unsprung weight reduction has made the job of the suspension in controlling the jolts over potholes significantly easier, and the Continentals have comparatively soft sidewalls helping a well earned reputation for ride quality.

Will there be a production run of the upgraded calipers if all goes well?

That is the plan. I always start with doing what I want on a project, and if it works out positively enough it may indeed go to production.

I have not weighed the factory cast iron calipers, but from unbolting them and supporting them by hand while still attached by the brake lines we know they are seriously HEAVY. Once we get them off the Ridgeline will do precise weight comparison with the planned upgraded 6 piston calipers, but I expect at least another five pounds per corner of unsprung weight reduction at the front end per corner. That reduction which will further help the suspension do it's job, giving both faster front end response and ride better too. And we hope to get a lot better brake modulation, particularly when towing (all the car magazines have the weak Ridgeline brakes as one of their few beefs ..and I agree).

Brake upgrade would be a welcome option! We have discussed this before but just to reiterate . . .GenI and GenII Ridgeline front calipers and rotors are (apparently) cross compatible. If you develop a product for the GenII it should also work on the GenI except perhaps the hose lengths. I don't know about the rear compatiblity. . . There are plenty of GenI's out there so it should add to your potential market!

Count me in if you do.

@Brian Goodwin at GWR regarding the wheels, have you confirmed the load ratings are equal to or better than the OEM wheels? Since this is a truck and may be subject to carrying heavy loads, wheel load rating could be an important factor a prospective buyer should consider.

I don't know about the G2 Ridgeline, but the G1 Ridgeline had a load rating of 902 kg per wheel (1989 lbs)

Brian - will you be upgrading the shocks as well with the lowered suspension, or is that not necessary with the RL? I am curious as I have read of others lowering the RL, but there is no mention of the shocks. Thanks

Just doing springs for now, though I have reached out to friends at KONI about potential to do more. That's all pie in the sky for now, but perhaps down the road.

Yes, as already noted in our other thread we have sufficient load ratings and the tires chosen here actually a bit higher than stock load ratings. Enkei makes the optional HPD wheels under contract to Honda, same process used to make these here, Enkei rates these for this vehicle and we have a few decades of working relationship with Enkei. In brief, Honda trusts Enkei and so do we.





Meanwhile today....more milling about. Somewhere in there is our first set of brake brackets. :)
