Cobra R pics....

RE: Cobra R pics....

after all the todo about which rotors to use, I ended up going with stock rep[lacements from Autozone because of their warranty. I needed to do something and the 2 yar warranty was an easy decision. I seasoned them, so we see ;) As fas as lowering it, I will some. I'm not looking for a scraping stance. This is just a daily driver, something to drive in all situations..the Stangs are for the real fun.
 
RE: Cobra R pics....

surely not following your logic. These tires are 1/2 shorter than stock overall diameter -26.1 vs 26.6. That means it is 1/4 lower in the wheel well. You are seeing that 1/4" in the front wheel well?? Since the car is "totally " stock at this point..how can you say it is higher thanstock? Like I said, I'll drop it some..sometime.
 
RE: Cobra R pics....

Here is the factory spec for stock height in front:

Since you have 17" rims the diameter is 1/2" greater then stock, so the measurement would then be 25 - 25.50. The different tire size makes no difference to the above measurement since only the wheel to body difference is measured. If you take the above measurement and get 25 - 25.50 then I apologize - it will technically be in spec. BTW - the rear spec taken exactly the same way is 1/4" less than the front.

Also, while I'm sure you haven't adjusted the sensors, I think they were likely set out of adjustment by either a previous owner or a shop that did some work on the front, (replaced bags, bushings, etc.?), and didn't get them re-adjusted correctly.

RE: Cobra R pics....

for goodness sakes.........rim diameter makes no difference at all. It is the overall diameter of the tire that makes the difference. You could have 24" rims or 14" rims. If the overall tire height is the same, the car knows no difference. This is basic. Not sure where you are getting your info......
 
RE: Cobra R pics....

and...if my tires are 1/2" shorter, because that is 1/4" top and 1/4" bottom, it would lower the fender lip height by that same 1/4", the difference below the spindle center. Hoiwever, since a stock tire is 26.6" tall, I do not believe you have an accurate measurement there. Not sure where you got it, but think about it. How can the tire be taller than your height spec?..unless the tire sat up into the fender, above the lip. This is not how these cars sit.
 
RE: Cobra R pics....

That picture is straight from the factory Mark VIII tech manual. Look at it closely and think about it - it's the only logical way to *measure* suspension height. The measurement isn't from the bottom of the tire, it's from the bottom of the *rim*. That's why tire size doesn't affect that measurement.

Using that diagram, notice that the measurement shown won't change at all whether the tire gets larger or smaller. If you measure it using the figures I listed, it will instantly tell whether yours is in factory spec or not, that's all. Sure, a larger or smaller tire will make a difference in the gap between the tire and fender, but not from the center of the wheel to the fender. The only reason they measure it from the bottom of the rim is because it's too hard to accurately measure from the center. And since your wheels are 1" larger than stock, I divided that by 1/2 and added it to the measurement.

All we're trying to do is help you understand how the height sensors determine the correct height for your suspension. Your car looks great, especially with the Cobra R's, but it's virtually everyone's opinion here that your front adjustments are higher than standard. We're only trying to help, and give the correct step for determining the proper height. Where you take it from there is up to you...

RE: Cobra R pics....

I didn't look at the pic close enough I guess. Now I see it is from the bottom of the rim. It is easy to change that to the ground. A 225/60 tire has a side wall height of 135mm; that is 5 5/16". So add roughly that much to the measurement and that is what the distance is to the ground. I fully understand how the height sensors work. No that you guys know this, but along with my restoration business, I teach auto at a high school. I fully understand what is happening there and I do inbyend to do something about it. My plate is so full you could not imagine. It took weeks to get the brakes and wheels on. I am restoring the following at this time:
1968 1/2 428 CJ-mine
customers 1968 1/2 CJ
customers 67 Fairlane
70 Trans Am clone -mine
1970 Datsun 240 Z-mine
1964 Thunderbolt Clone -businesses
these are active restorations along with regular life stuff..I'm busy :D I will get some time to deal with it, right now I'm just happy the wheels and brakes are on. I have to find a left front brake pull ( very noticeable at the slightest tip in of the brakes ) and get the car inspected. Bust busy busy..Thanks
