Great pictures. Very cool.

You chose to go with thinner tires at the front?

For a Second I thought those wheels where from the LFA; looks similar. Anyways it does look really nice, a slight drop will make them look even better.

Not that big of a deal, but it looks like you went from OEM 255mm on the front to 245mm. That essentially reduces the contact patch on the front especially if you are on the same width wheels (which looks like you are at 9 inches).

Probably, you will not feel much of a difference unless you push the car after entering the corner hard as you might feel some understeer due to less contact patch on the front. I guess, you can always go slow-in and fast-out, which is very natural to me coming from FWD cars all my life.

How do you like MPS4S vs the OEM MPSS tires your car came with?

Brother I don't know what to tell you about Contact Patches, but since getting these I've driven the car twice as hard and fast than I did with the OEM setup - and truthfully felt it has a wider / stiffer stance that gives me much better control than it did before! Honest to goodness brother!
Yeah, while taking break from project related work items at the office, I open this page every so often to see what is going on.

I know we got to see these in person before they shipped out but theres nothing like seeing it on the car. That blue with the black chrome looks INSANELY good. I am glad we decided on this finish, it was a risk, but did it ever pay off!

Those rims look really good. The orange calipers look cool also!

My Calipers are black. I am thinking when I do get rims they will be black to match the car. I think red calipers would look the best on mine, not sure if I would ever change it though. Personally, I like the orange ones one yours!

Wish I had orange calipers instead of black! Right now my car looks to much like a plain RC with a 4 or 6 banger underneath the hood. Maybe if I had orange calipers, it would help the car to be recognized as a F car!
Since RCF's are so rare, I don't blame people for not seeing my car as a higher end RC car. Is Lexus even selling enough RC cars so that they will be continued to be sold for the net 5 years or so?

Either way, go with the Wheels that YOU like best, and NOT the ones others tell you would fit or look best on YOUR car brother! In all honesty, Im baffled by so much talk about "Contact Patches" on tires etc. Im sure we can all agree that Car Companies put their recommended Wheels & Tires on them when sold. Certain sized wheels & tires wont fit "properly" -which is the Offsets, and something I always deferred to the Pros to configure. Im just not able to comprehend such stuff. By going from the Stock 19" staggered wheels to this 20" set, I "personally'" have a better feel to the car. (Would love to hear how many other Members got the same Stock Wheels I did when purchased new. Not sure why Lexus charges so much for them, I think they're awful) For years I read that going to a lower profile tire sacrifices ride comfort -which is understandable. However, I truly don't feel any loss whatsoever!

Overall I am extremely pleased with the way these Wheels & Tires look, feel, and perform under a heavy right foot! As stated above, the only ***** I have is about the ridiculous amount of Brake Dust these pads put out! Anyone reading this who has suggestions on how / what I can replace them with to rectify this problem PLEASE send me as much info as possible, either here in my Thread of via PM. (Links please?) Despite PK Design "Ceramic Coating" these shiny Wheels, keeping them clean is a true PITA! AutoGeek must think I'm using MicroFiber Towels as Kleenex the way Im going thru them!

Stay Safe & Stealthy !
Orange calipers are a $300 option.
Black is standard.

Look up TSB for brake pads to address brake dust if you want to go the costless route.
Otherwise get aftermarket pads.
