22" Vossen CV4 Matte Graphite Machined finish. What are your thoughts?

at first glance; a modified RDX is a in my book.

on closer inspection; the straight spokes dont flow well with the curvy lines of the RDX.
however; you'd still get a honk and a wave from me!!

I agree. Would love to see more mods available for Acuras.

That looks hot!!! I'm on 19's and I can only imagine what 22's would be like on bad roads.

I think it looks pretty good. We just traded in our 2010 RDX that had 20x8.5 +35mm offset for a new 2015 RDX awd/tech. It rode great, although the first gens did have a harsher ride. Anyhow, we will be going with the size and spec wheels on the the new one with a 245/45 tire.

What profile tire? Increase in unsprung weight? Handling has to be impacted, and while I like the RDX, it clearly isn't all that flat through corners. Oh... And tire cost for the 21"s?

This might sound like a dumb question..but when the larger wheels are put on,does that mess the speedo calibration?

Also,is the ride harsher with the low profile rubber?


Thanks,
Steve

Comfy

I believe if you increase the outer diameter it will mess with the speedo / odometer calibration. If you increase the rim / alloy diameter but make the rubber low profile so that outer diameter remains the same as original, it should not affect any calibrations but may give you a much harsher ride (but look really cool)!!!

Steve,
Not if the correct aspect ratio is chosen to match the larger rim. In other words the tire diameter remains the same but it will have less sidewall. It will ride like a chuck wagon with 22" wheels. 19" wheels would be about as large as you'd want to go without sacrificing too much ride comfort.

+4 is a lot! Rubber bands on the rims for tires...

Average price of stock size tire - $159 ea. Plus two size(20") of same brand and make - $196 ea. Plus four(22") would be rather pricey only due to the limited availability of tires in that size. Unsprung weight in this type of vehicle is a non-issue as this isn't a sports car, coupe or sedan. Most SUV/CUV's made today come with 20" wheels rolling stock. Wish ours had.

I would like to see more aftermarket support for the new RDX as well. Realistically, I don't ever see this happening because it is not as "sporty" as the first gen. IMO the second gen has matured quite a bit, thus appealing to a different audience(older).

Looks nice!

Unsprung weight is a non-issue? Physics is physics...still the same affect.

True, but I doubt anyone will be dragging, tracking or auto-crossing this behemoth. The only ill effects I noticed on the previous gen RDX with plus two sized wheels/tires was a slight tramlining on uneven roads and a slight increase in road noise. 0-60 was the same as was gas mileage. This was of course before the Hondata reflash. After, it was a whole new beast

Stock wheels weight= 27lbs / MRR Designs HR2 20x8.5 wheels weight= 31lbs. Thinking about going with some Enkei's with the same size and specs on the new one.

You can gain benefits from decreasing un-sprung weight on any type of vehicle. If you drop 5-10 LB at each corner (including tire weight), you can easily gain 1-2 mpg in fuel savings and improved acceleration. Doesn't make a difference if you race or not.

I understand that, and I'm not disputing that. I am just simply saying that the trade-off when going with plus size wheels and tires is so minor considering what you are gaining in the looks department. Most people that do go this route are not so concerned with acceleration or the minor decrease in MPG's. Those that are should look into the lightest weight wheels they can find.
On our first gen. RDX, both on paper and the on-board computer showed no decrease in MPG's. I'm sure acceleration was affected however. When I added the Hondata Reflash, MPG's went up, acceleration went up and overall HP went up.

Sculldog3

It's not minor. Seems like it is since it's only 5-10 pounds, how much could that matter right? The thing is, suspensions, shocks, brakes, everything that steers and stops is engineered in with the existing 18" wheels in mind. Unsprung weight adds some inertia, makes the steering less responsive, and absolutely means a slower car - it has to, physics and all. I get folks like the look, but you can't say it has no impact.

Murrow

It's not the acceleration but the braking that would concern me. That said -- looks good!

hondu

I believe I have read before that losing 1 LB of unsprung weight is like losing 10 LB of sprung weight. So dropping 20-40 LB of unsprung weight would be like losing 200-400 LB of sprung weight. While I think 10X is an over-estimation, I do believe there is a multiplier effect when reducing unsprung weight.

Don't you wish we didn't have that gadawful front plate here in Texas? Silly state we live in. Wish Rick could get rid of those on his way out...

Yes sir, I do. I hate having to put one on my Z! But it's my daily driver. I have a plate mount that screws into the tow bracket mount fortunately.
