Letter Number 2
Ok if you haven't noticed yet that none of my forms give any indication they have been set (I am working on a solution), till then if you hit the send button, it sent it. If you do not wish to recieve this letter either E-mail me at and say "unsubscribe". or

Ok today's topic is: How does the appearance of your car affect your performance. (Such as lowering, various size wheels, and ground effects. Below
Apperance and Performance

Ok now: do things like lowering hurt performance. It depends. Ok lets take a stock 1989 Mustang LX, 5oh, 5-speed. Ok the LX's performance numbers:
0-60 mph 6.4 sec
0-100 mph 17.3 sec
1/4 Mile 15.1 @ 93.2 mph
Top Speed 147.8

Ok now lets say you want to add ground effects. Ok so we'll use the Mustang GT as an example. (The extra body pieces added to the GT are ground effects, but you knew that right?)
0-60 mph 6.5 sec
0-100 mph 18.0 sec
1/4 Mile 15.2 @ 92.0 mph
Top Speed 140.0

Ok so what happened ? Well first off the ground adds weight. (weight=evil) Ground effects also adds extra drag. So ground effects are bad right ? It depends on the car and what you want. The ground effects help handling if the car is lowered, the ground effects also can help acceleration to. Now if you notice the only big difference is top speed, but how often are you going to do 140 mph ? So if you like the way ground effects look get them, they don't make enough of a difference in acceleration to care and will help your handling.
Ok next: how about lowering your Mustang. Ok now lets say you buy lowering springs for your 89 Mustang GT (1.5 inch). Ok now if you compare the chart below with the stock GT numbers Above you will notice that the car is just a tad bit slower than in the stock form. Ok but, this difference was made up on the skidpad. The lower you go, with in reason, the better the car will handle. With the 1.5 inch lowering springs the car picked up two g's and 1 mph on the skid pad.
0-60 mph 6.5 sec
0-100 mph 18.1 sec
1/4 Mile 15.2 @ 91.9 mph
Top Speed 139.0

Ok next: Do you wonder how 16's might affect your car's performance or maybe 17's ? Ok now first off obvisuly wider is better. The wider your tire is (within reason) the quicker your car will hook up hence better acceleration. Also the wider the tires the more your handling will improve. Ok the stock Mustang GT comes with 225/15/60's.

For those of you who don't know what these numbers mean here it is:
The first number (225) is how wide the tire is.
The second number (15) is the height of the wheel
The third number (60) is the height of the actual tire.

Ok here is the stock GT performance numbers again:

0-60 mph 6.5 sec
0-100 mph 18.0 sec
1/4 Mile 15.2 @ 92.0 mph
Top Speed 140.0

Ok now lets say you change from a 225/15/60 to a 225/16/60 now look at the difference.
0-60 mph 6.5 sec
0-100 mph 18.0 sec
1/4 Mile 15.2 @ 92.0 mph
Top Speed 141.0

As you may notice the results are virtually the same (17's,18's, and even 19,s had similar results). Now keep in mind these all these tires were 225/ x /60's. Overall remember that this car was stock and the tire changes would have made a bigger difference on a modified car. In genral a shorter tire will make you quicker and a taller tire will give you more top end.
I would like to give props to Doug Dalrymple. I recieve some rude comments from Chevy, Chrysler, etc. fans, everynow and then, but, Doug, a Chrysler owner, was very polite and even signed the guestbook. Thanks Doug Dalrymple.
Can't find information you need ? Since it takes alot of work and time to post all my information E-mail what you want to know to and I will write back.
Oh well that's it for now.
