Compared with the stock '94-01 tire sizes, those tire sizes add 0.18 inch in height to the front and 0.16 inch to the rear.Autophile said:I have a 91, stock height, with Toyo T1-S 225/45-16 on front, and 255/40-17 on rear (94 OEM wheels). My measurements are:
I know my tires are not the stock size, but hopefully this will help you.

I suggest that you refer to the tech. manual found here on Prime's home page for the correct method of measuring ride height. That's the best way to do it.
BTW that is a really nice photo of your car.
The FAQ gives diameters 23.1" front and 24.9"rear for 1991-1993, 23.6" and 24.7" for 1994-1997. So the difference in height associated with going from OEM 15/16 to OEM 16/17 is +0.25" front, -0.1" rear.Autophile said:The height spec in the manual is for a 91 with the 15"/16" wheels and tires. How much height difference is there between that tire/wheel combo compared to the 94-01 16"/17" dimensions?
Yup. More precisely, it's +6.95 mm (+0.274 inch) front and -1.8 mm (-.071 inch) rear.Tom239 said:the difference in height associated with going from OEM 15/16 to OEM 16/17 is +0.25" front, -0.1" rear.
Interesting question.Tom239 said:The specs on page 18-6 in the 1995 manual are the same as in the (online) 1991 manual, despite the different tire sizes used in the two model years. I've never known whether that is a lapse in the manual, or whether different suspension parts offset the tire size differences.
Still a good question. Let's get Larry on the phone...Tom239 said:I'm still interested to hear any thoughts on the question I'd asked earlier on in this thread (what causes low ride height--can old shocks do that, or ...?) .
Good point. I measured in my garage (concrete floor). It's reasonably flat (shows very close to level with a carpenter's level) but I can see how a dead-flat surface would be the ticket for this measurement.Larry Bastanza said:When you say your spec is off, do you really have any idea if the floor you are measuring on is flat? You really need to do this on a rack for this purpose or a perfectly level concrete pad found at many racetracks.
