Default lowering vs. larger rims

Would I get the same effect by puttng 18 front and 19 rear rims insted of lowering my stock 99' vert? If I end up going with larger rims will that screw up the spedo or active handling?

The answer is no to spedo changes so long as you keep your rolling diameter.Here are two pic's of my car with 18s & 19s and then lowered with 18s & 19s.

with 18s & 19s


18s & 19s & lowered


After the suspension has settled.


Finally how it looks today .

I read the question as Tdog/stinky asked it - the difference between
17-18 wheels lowered and 18-19 wheels stock height.
Right?

Yes and the first picture is of 18 - 19 stock height, I then show a picture of 18-19 lowered and answered the his question reguarding speedo effect . If you want I can post a pic of stock wheels lowered.

I think you are asking if the 19 & 18 will give you the same effect as lowering your car with it's OEM 18 & 17's.

If that is the actual quesition, the the simple answer is NO.

Most likely you will end up (if done properly) with the same size (diameters) or very close when you go 18 & 19 as you had when you were 17 & 18.

SO the answer is NO to your question. Your car will be the same height.

All you do when you go with bigger wheels is end up with less sidewall tires. More wheel less rubber.

Example
Rears
C5......................C6
275/40x18 or 285/35x19

Fronts
245/45x17 or 245/40x18

These comparisions which are OEM C5 & C6 sizes are just about identical in diameter, just more wheel and less rubber on the C6 sizes

Or can you inc. the wheel diameter, to fill the gap...

Throw 19/20s on it, AND lower it a couple inches.

overall tire height plays a lot into how big your fenderwell gap is. there are many 18" tires that are taller than 19" or even 20" tires.

so while one might think that a 20" wheel would be bigger in the wheelwell, in actuality, the 18" wheel/tire (if it was taller to begin with) would have a smaller tire to fender gap.

Don't mean to hijack the thread but are either of you having problems with your chin splitters scraping using 18/19 and being lower?

It is obvious, especially with the yellow car that it would create problems. Your driving style would be altered quite a bit with a C5 that low combined with the ACI spoiler

Actually IMO , if you add larger wheels and don't lower it, it looks worse than with the stock wheels not lowered.

What I would recommend is lowering your car all the way on stock bolts (without cutting bushings , just bolt adjustment) and let it settle a few days and see how you like it.
Obviously lowering the car you are going to have to adjust your driving style and be more cautious...but just how low you go is up to your own personal prefernce. Tom's car (Y2kvert4me yellow car shown) is pretty slammed and he has a chin spoiler, so yes he scrapes a little here and there but his car looks Great

Here are some pics of my car. Just lowered on stock bolts was low enough for me. I am running 19's all around.

Remember, that compared to the stock, forged aluminum 18s and 17s, many aftermarket 19s and 18s will weigh more (increase in unsprung weight), creating a harsher ride and with more rotational mass, hurt acceleration and braking somewhat. I've spoken to more than a few people who went "big", only to return to stock, primarily because of the reasons mentioned.

The way I'm reading the question, the answer that going to 18/19's without lowering, is that the car will actually be slightly higher than stock. Even higher yet than the stock diameter rims with lowered suspension.
