Ok, not bad. But like you stated, maybe not an everyday color scheme lol.

What do you guys think about the Cosmis Racing MR7's???

I really love the look of the deep concave. I think it will look great with the CBP Si. I don't know too much about fitment or if it would clear a BBK? Can anyone give me some info?

To those who installed significantly-lighter wheels -- do you guys notice any increased harshness in the ride, especially on parts of the road where there are small frequent bumps?
I was seriously considering lighter wheels, but what stopped me (other than $$) were some concerns about such harshness increase and the road "beating" on the suspension elements more than what Honda designed (with heavier wheels' inertia "absorbing" more of it), potentially to the point of affecting the car's long-term reliability... I know it's been talked about before, but still -- any fresh thoughts on that regard?
Actually with lighter wheel you will get a better ride as well because suspension will have to work against small impact forces.

Here. Educate yourself!

I have significantly lighter than OEM wheels on my SI (going from 28lbs on OEM to 16.9lbs on the new wheel). I think I posted this before but...

The car is not noticeably faster nor does it feel to brake any better. I think you'd have to track it with a stop watch to notice these improvements, they're probably there, but on the regular street I don't feel it. What I can feel is the suspension "feels" tighter due to the components "responding" faster on bumps or imperfections in the road. I think if you exaggerate the explanation out it would go: the OEM rims being heavy the suspension feels lethargic to the road while the new lighter rims feel more tuned/active/energetic.

But I thought the ride with the heavy wheels was still good and solid. its just even more so now with the new lighter rims. I would not call it NIGHT AND DAY difference though. If you didn't pay attention to the suspension and ride when OEM, I doubt you'll feel anything with the new.

Lighter wheels in my experience with several cars now have zero down side (as long as their quality rims to start with). I'm a big fan of enkei's so I've kept with that brand (not that there aren't other quality wheel makers though).

They've got function, but its mainly for looks. my 2 cents anyways.

I beg to differ. You are telling me that you didn't feel any difference dropping almost 1/3 of weight per corner? I dropped about 8 pounds per wheel on my Accord and the difference is pretty significant. You can't argue with science. I mean they predicted the solar eclipse to the minute in 1979.

I'm not arguing with science at all. I'm telling you what "I" noticed with my setup and with how I drive. I'm not tearing through the streets with my car, or racing others, or auto-x'ing, or driving "like I stole it". All of which if that is you're cup of tea I'm sure you would probably feel a bigger difference between the two.

Wow! You sure do like to assume lot of stuff about other people. You can notice the difference in day to day driving like taking a on ramp, merging, breaking and accelerating. Those are part of normal driving too.

Someone asked for information based on those who actually installed said wheels on this car. Being I did just that, I replied in the spirit of offering my specific experience. I never claimed to be the definitive know it all about anything.

If you can feel the difference, great. I can not. Even as such, its not like putting lighter wheels on your car instantly turns it into a monster machine. To each their own.

Thanks but that's not what I was asking. I've "educated myself" a little bit before (via sources that are a lot better than your video, i.e. targeting a more technical audience instead of "general consumer" like this flashy clip), although I'm quite far from claiming any level of expertise on the subject matter. I am very well aware that lighter wheels => better/"faster" handling. My question (hopefully to those who actually know this subject really well) was with the lighter wheels potentially "beating" on the suspension at a higher rate than what the engineers had in mind originally with their reliability target numbers.

In other words, I'm not sure what played the biggest role in how the stock wheels were picked. Was 99% of that decision influenced by other factors, like cost, driving dynamics, balanced ride feel, road noise, etc., and 1% by long-term reliability? Or is it even 100%/0% (i.e. the effect on reliability of suspension elements is absent or negligible)? Or (and that is my concern) maybe that ratio was as large as 80%/20% or 70%/30%, i.e. opting for lighter wheels/tires would make a noticeable difference on the suspension elements' "wear and tear" several years down the road?

Bringing this thread back from the dead since I am also looking at the same wheel that the OP posted. I have always noticed improvement in overall performance of my previous cars when installing lighter wheels without affecting reliability of other parts of the car. That being said, it is interesting that Honda chose a heavier wheels on the Si, one the heaviest wheels I have ever had stock.

I dont have an answer to your question on why Honda would choose such a heavy wheel, maybe someone with better knowledge can give a definitive answer, but could it be that the heavier wheel was chosen in order to reduce Torque Steer? Or, Honda knowing that a large percentage of Si owners love to modify choose a heavier wheel to save on cost of the car knowing enthusiast would change them anyway? Does anyone know the wheel weight of the option HFP wheel?
