Depending on the brand, sidewall angle and shape can vary between tires . In any case, I've found the following sizes to be an excellent choice with regard to fitment and performance : front/235 , rear/275 . Also, if in fact the fronts are 9 inches wide, you're going to have clearance issues as well . You'll need to lower the offset in order to gain enough inner clearance . However, the trade off will be, that the wheel may then protrude too far outward - causing clearance problems with the fender lip . A 9 inch wheel is not a good choice to use up front on a 986 boxster . Regardless of what spacer you use, I don't think that it will fit .

I must have had a brain fart, I looked at the boxes again, and the fronts are 18X8's with a ET 48. I don't think that I will have to put spacers on the front with those. Thanks for the help Johnny D!

If they're 18x8 +48 then you're good. However, ultimately you may find that the fronts look quite a bit "in" as compared to the rears . In which case, adding a 7 - 10 mm spacer will bring them out nicely .

p.s. Try contacting this member, Allen K. Littlefield . He recently found an excellent source for spacers at very reasonable prices.

I am still wondering what size spacer I should get. I'm afraid the 7mm won't give me enough clearance over say a 10 or 12, yet I don't want the outside lip sticking to far beyond the fender. Has anyone had any problems with something this size rubbing on the outside? Johnny Danger, what size rims are you running on the rear? What is the ET? You mentioned running 275's on the rear, is that a 30 series or a 35? Once again guys, thanks for your help!

I run 18x8.5 et 55mm in the front with no spacers and 18x10 et 48 with 5mm spacers in the rear. I perfer the fronts to have the tucked in look. It makes the rear of the car look much wider.

TriGem2k what size tires are you running front and back?

I have the following wheel fitment :

front: 19 x 8 +31 et 235/35/18
rear: 19 x 10 +31 et 275/30/19

Keep in mind, my set-up is very aggressive, and my vehicle has been lowered via adjustable coilovers . However, prior to this, I experimented with different wheel
sets, along with different suspension configurations. With that said, I can tell you from experience, if you're using a 10 inch rear wheel, I recommend targeting an offset between +40 to 45 . As far as the fronts are concerned , depending on the look or stance that you're trying to achieve, with an 8 inch wheel I would recommend offsets ranging from +38 to 40 or so .
