Flying Dutchman

Hi all,

I wonder if anyone could share his experience using 18 inch wheels; offset front 45, rear 50 on a boxster S my 01 (nice 3 piece speedlines ).

Would I need spacers is the big question i guess...

Thanks!

I doubt it. i think 47 or 48 is the correct offset for 10s. Suncoast sent me 17mm spacers to make my 18 x 10 ET 65s work

Beautiful wheels BTW

Thanks for the info! Yep, the wheels are very nice...

What widths?

Car is at my local P. specialist, will check. I'm a bit uninformed about all the variables involved...
The offset in combination with the width will clarify if this will work on a 986S I take it ?

Thanks

My boxster came with 18's.. 7.5x18 front and 9x18 rear. The 9's had, iirc, a 52mm offset. I think some challange with 10's and wider in the rear are 1) hitting the springs on the inside and/or 2) hitting the outside fenderlip. What size tires will you be using? 265? 285? even larger?

I've just recently figured this out, since I just added this 01 S to my garage. If those are the 18 inch speedlines that i've seen before they should be 10s. It is hard to get anything bigger than 265s on 10 inch wheels under a Boxster, but it can be done depending on the tolerances of wheels and tires. i have 275 35s on 18 x 9s, but they won't work on 18 x 10s. Anything other than stock suspension could also cause you issues. i am going to put 18 x 10s with 265 35s as soon as these tires wear out. The new wheels have an ET 65mm offset, so I bought 17mm spacers from the dealer. The parts guy said they would work with the 2 piece lightweight BBS wheels, but I am sort of eliminating the weight advantage by using spacers and 2 pocketsful of nuts and bolts. The wheels are just too nice not to use them though. I should try to find someone to trade the 996 wheels for Boxster sizes, but I may want to use them on the 996 at some point. Spacers can take me one way but not the other.

My 18 inch speedlines will run with 225 front and 265 rear, this should work then with the offsets 45/50 as i understand.

Thanks.
