Suggestion

My experience with big brakes/tightly fit wheels is that the brakes usually are designed for a barrel size� so you could measure and confirm, or look at the brakes usually equipment on the boxer and compare to the 996 (just check caliper and rotor size).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I know, I know -- it will look terrible But I do do a lot of backroad driving and some of those roads get pretty rough and I'd rather be taking the Porsche than the family Toyota but the 18 inch rims are just not made for rough roads I have an opportunity to buy (at a pretty good price) some early model Boxster rims they are 16 x 7" on the front with a 55 mil offset and 16 x 9" on the rear with a 70 mil offset will these fit on my 2002 3.6 Targa (narrow body) ? I suppose one of the things I worry about is whether or not the brakes will fit inside 16 inch rims? If the offsets are a little bit out can that be fixed with spacers? Thanks for the advice -- have looked and done searches but I just can't seem to work it out.

POST 2Original post

No, the 16" wheels will look great. I did 13" wheels on my '04 996, added with fat tires with high side walls and and see how good it looks? Then you could jack it up and add a few other gizmos for some off roadin' fun! I finally got it to look just like Ferry Porsche had secretely envisioned, but was afraid to admit! OK seriously, I don't know if the 16" wheels will fit over the brakes. I "think" they will but am not certain.

POST 4Original post

Another option might be to use 17" rims instead of your 18" wheels. I must be in the minority because I still ride on 17" for my winter tires and summer tires. At least I know they will fit over your brakes.GL Michael.

POST 5Original post

I'm pretty sure 16" will not clear the brakes, go 17"

POST 6Original post

Yeah, I've never heard of smaller than 17" on a 996. The alternative is to just go all out, this is what I thought of (kind of like Tim, but not on drugs).

POST 10Original post

Now that I think about it, 996's have Boxster S brakes, you cant put 16" on a Boxster S so they will not fit for sure. Tim, Too bad there are no real flames on the Honda! uhhh yeah, got any to spare

POST 11Original post

Wow, I got enough grief for staying with 18s . . .

POST 12Original post

there not made for 16 inch wheels,17 or 18 thats it dont read into it....that is all

POST 13 / ORIGINAL POSTEROriginal post

OK... OK... will look for 17's

POST 14Original post

I have a set of 16"s for my 944, and they would not fit over the front brake calipers. Rears fit fine. 17" is as small as you can go in the front.

POST 15Original post

I couldn't get my 16" 944 club sports to fit. It was close though! I had a flat and wanted something to leave the car sitting on other than that stupid spare.

POST 16Original post

I�m sorry for replying to such an old thread. I�ve been thinking the same thing recently. There�s a post on a Japanese car forum showing a 996 Carrera fitted with 16-inch wheels of 986 boxster. https://minkara.carview.co.jp/smart/...3215/note.aspx The inner rim diameter of the 986�s 16-inch wheels may be larger than that of aftermarket ones.

POST 17Original post

I think it looks pretty good actually. The car is definitely lower than it looks to clean up the fender gap. My experience with big brakes/tightly fit wheels is that the brakes usually are designed for a barrel size� so you could measure and confirm, or look at the brakes usually equipment on the boxer and compare to the 996 (just check caliper and rotor size). There is enough gap in most 17� wheel photos, more than 1/2�, that 16s should work. BUT, the issue once you get to that design diameter is usually caliper to spoke clearance, as spoke angle or location gets more pronounced to meet the wheel offset at the barrel, and with less diameter to work with, so getting a working fitment can be tricky. So for 16s on a 996 the correct answer is probably �sometimes�. Some will fit and some won�t, and it may be hard to determine without fitting them. Depending on pattern, even offset may not offer much clarity. Newer designs do pay more attention to caliper clearance, as newer cars have bigger brakes, but there are less and less 16s, and getting the range of width and offset to fit these cars, in a 5x130, won�t happen by accident. I got a set of 17� Porsche 10 spokes as a second wheel fitment. They were the lightest wheel sold on this car as far as I know, and with sticky cheater tires they should be very responsive and compliant in our local rough autocross courses. Those compounds will offer plenty of grip for 300hp.

POST 18Original post

I got rid of the 18� wheels (5 spokes) and replaced them with a set of factory 10 spokes in 17� diameter. The 17� tires have a bigger sidewall and ride slightly better, but my speedometer reads about 5 mph low now. The 18� wheels I took off had been damaged by driving through potholes in the streets around here. I think the car looks a lot better with the thicker sidewall tires used with the 17� wheels. Be careful and get wheels with the correct offset for the 996. Wheels from a 987 or a 997 won�t fit without using wheel spacers! Ask me how I know.

POST 19Original post

Brake caliper clearance is the biggie if bolt spacing and hub diameter match.
