Help with wheel size/spacers please!

2002 boxster s - stock suspension
Bought OZ alleggertia wheels with tires and not sure if I need spacers.
Wheels are enroute now.

Sizes:
front 8.5 x 18 et 53 with a 235/40
Rear 9.0 x 18 et 43 with a 265/35

I know the back should be fine but will I need a front spacer?

Thanks for the help.

To be frank, if you need spacers, you're installing tires/wheels that you probably should not be installing on a stock vehicle. My primary driver is a Dodge Ram 1500 Sport. 10" wide tires all around. Not recommended. My Boxster, has stock specs for tires and will remain so because, adding spacers changes the spec enough to effect both handling and tire wear. It might look cool but, if you go through tires faster or damage the body work it's not a good idea. Also, spacers tend to flex which can result in very expensive damage over time. Just my opinion so, take it for whatever it might be worth.

More to the point, if you end up needing spacers, you've altered the wheel base which means, major adjustments to caster/camber settings and may result in early bushing/shock/strut failures.

Spacers won't alter the camber or caster setting and there is no caster adjustment anyway
Don't know what kind of spacers you are referring to that flex??
Effect handling, sure a little, tire wear, I'm not so sure

Put in your new info as well as factory info and you will see what you need
