    Sandlasted plexiglass or lexan?

    No, but to some degree yes.

    No, but a coating of a type may be applied, not sure yet.

    Betting it's gonna involve lights around the spare tire through the spare tire cover.  Didn't I send you one of those lights I had made up?  Might be the time to play it.

    Bingo & possibly the later that you mentioned! Haven’t worked out the details yet! And yes you did & again thank you. 

    New hardware is being designed & hopefully will be built this winter, but not sure yet how it will evolve.

    To give this some perspective, this piece is 26” long 11 1/4 “ tall.

  2. So some may remember the trunk cover for the spare tire/battery.

    And while I originally thought it was ok, as time moved on I knew I wanted to do something else, but I couldn’t exactly see what that was to be. Now I have.

    so I needed to remove all the old hardware & start sanding & sanding. Any guesses as to what’s next?

  3. Paul as you step through this & weight what you want to do here are a few things that might help.

    For instance if you want to push the wheel out & ultimately make the rim wider you can build a cheap wheel spacer to place between the rim & brake this will allow you a visual of what it would look like, plus it allows you to visually see how wide you can make the rim. Also if you want to keep the original wheels, but can’t find them in the width you want you can have the original ones widened! I have done this for a couple guys over the years. You just split the original, cut the two halves apart at the drop in groove, roll a piece of flat hot roll stock, weld it all back together.

    Thank you kind sir😊

    I was actually thinking of doing the wheels/tyres first, then do the measure up to see what limits I had left before changing the suspension (if at all).

    Like the good gyno says, I’ll look into it 👌🏼

    I understand why you would want to do it that way. And there is nothing wrong in doing that if you so chose, but, and this is nothing but a question. How are you going to know what to chose for rims & tires for a change you haven’t made? The link that I provided allows you to play with rim & tire size as well as alter suspension parameters to see where there could be interference. 
    You indicated that you would like to lower the car. That being said, suspension restrictions always become more limiting when lowered, due to downward travel, not upward & the greatest movement is downward.
    So my only reason to mention this method for choosing rims & tires is, unless you have a way & knowledge of how to look at the triangle axis of suspension movement that you intend to make you won’t know what it will be. Even if you make it with your current wheels!

    I may be saying this wrong so please pardon me if I am.

    Hey Fitzy,

    Thanks for your reply.

    From the specs I’ve read mine is 5x 4 ½” (or 5 x 114.3 in our terms)?

    However, I will be careful as wouldn’t be happy to lay out $$$ & have to raise it 4” for clearance.

    First of all welcome to our obsession Bonne61! 
    The very first thing you will need to do is make very accurate measurements of fender clearances, wheelwell clearances, offsets, suspension clearances, etc… if you are going to make changes to the suspension as you indicate that will effect those clearances, make them first! Unless you are really good and know how they will change the geometry of the car, don’t guess! After that start figuring your wheel & tire change. 
    That said in general most tire & rim combos usually end up pretty close to the same overall diameter, irrespective of rim size. What affects clearance issues more often than not is way to wide of a rim, like 10” or the offset being to much the wrong way. 
    So make good measurements & plug them into the attached link in the appropriate places & you will see what you can & can’t do! 
    https://www.wheel-size.com/calc/

    An example of my statement is this, my factory rims were P225 16” x 6 with a 43 offset! I had custom rims built. 18” x 8 with a 10 offset for the rears & 23 offset for the fronts. The tires for all 4 rims are P245 45 18”. Yet the over all diameter of the rim & tire combo is exactly the same outside diameter as the 16x6 with P225 tires. All I did was fill as much of the wasted space between the outside fender lip & the inside suspension/inner fender as I could with out making contact with any thing!

    these are the original rims/tires
