More 19 inch rim help for my 06 Boxster

[ethandelacroix]

Hi everyone,

I am new to the forum. I just purchased a lapis blue 06 Boxster. The first mod I would like to do is slap on some 19 inch rims. I have an opportunity to get a set of iss forged complex wheels in gun metal grey.

I have searched this forum and others. My question is what width should I go with for the rears? My choices from searches and rim manufacturers are 19x10 with either a 42mm or 36mm offset. I can possibly get a 19x10.5 with a 43mm offset similar to the wheel dynamics rpk-038.

As for the tires I will go with 265 35 19 with the 10" and 275 35 19 with the 10.5".

For the fronts the options are 19x8.5 55mm offset, 19x8.5 53mm offset, or 19x8.5 45mm offset.

Tires will be 235 35 19.

I would like to choose the right width and offset to have the tires as flush to the fender as possible. I do not want to use a spacer and haven't thought of lowering the car as yet.

I would love some advice to this so I can email my friend to get the rims started.

Thanks in advance.

Even if you don't end up buying from them you can get some great information, ideas and pics of the cars with the wheels on them at www.wheelenhancement.com

Based on your information, I would recommend the following fitment :


Fronts: 19 X 8.5 +45mm offset
Rears : 19 X 10 +36 or +42mm offset (it depends on how aggressive you want the fitment to be)

Tires: 235 up front and 275 on the rear


* A 10.5 inch wheel will fit on 987 platform vehicles, however, it's not necessary to go so wide .

Thanks Johnny Danger for the information.

What do you mean about aggressive fitment? I would like to go as flush to the fender as possible without rubbing.

I know that you think that 10.5 is too wide. With your expertise, would it be possible to let me know what the best offset is? Can you also let me know what the offset would be for an 11" wide rim?

Thanks so much for helping out a newbie

Well, in order for me to make a more precise recommendation, I would really need to assess your current fitment and make some calculations from there . In any case, as I previously mentioned, 987 platform vehicles can accommodate a much larger rear wheel than the 986 can . And it's not uncommon to see 987 boxster and cayman owners equipping their vehicles with 10.5 and 11 inch wide rears . However, most of my experience is with 986 vehicles . Therefore, the recommendation that I made was based on the available choices that you provided . With that said, 19 x10 +36 offset wheel will be slightly further out toward the fender than the 19 x 10.5 +43 will (and I assume that's the desired look that your going for). Moreover, it will give you approximately
13 mm's more of inner clearance . This can be crucial if you ever decide to lower your vehicle with adjustable coil overs. As far as an 11 inch wide wheel is concerned, again without being able establish a baseline of information, it would be difficult for me to make a recommendation .

A good forum to query would be Planet-9 . That site consists entirely of 987 owners, and I'm sure that there are many members who can provide definitive answers to your questions .

Just FYI,

I wouldn't recommend any more than a 10.5" rear set-up as an 11" will either rub on the inside in order to clear or will stick-out around 1/2".

Here are two 986 Porsche cars each using the same RPK-038 Wheels using the same 19x8.5 (45) & 19x10.5 (43), Tires: 235/3519 & 275/30/19....

that's great.
i saw some of your posts on the pelican forum, and i really love the wheels you have.
might even buy a set in the future (depends on the discount ).
this is a great forum (most active in the boxster community) with great people.
so i'm sure a lot will be interested.
