Which Alloys For A '90 Corolla?

[XkillerX]

Hi everybody,

this is my first post here, so thanks in advance for reading it.

I drive a 1990 Corolla Sedan XL (the classic) and was hoping to get a '97 celica this year, but it looks like that ain't gonna happen

So, i decided to visually tweak out my faithfull baby. 1st stop, are of course, alloy wheels. I found a set of great Borbet 6 spokes in excellent condition, but they are 15". My friend is a mechanic, and he says those wheels will rip the car apart unless i change the complete suspension and wheelbase system (something like that), and that anything more than 14's is pushing it too far for the poor car. On the other hand, on sites like tirerack.com, there are no warnings even for 215/40/16 wheels and tyres?!?! (which, according to a couple of calculators, replace the factory 155SR13's perfectly).

Does anybody has real-life experience with this subject? Should i stick to 185/60/14 or go ahead and try larger ones? If so, what modifications or repairs can i look forward to in the future?

Thx folks. Cheers.
