225/50/15 tires all 4? and Corsa Dash question
Posted by: brocklanders ()

So I've got a few projects on the go, mostly the kind of stuff that can be done inside nice and warm in these wonderful winter days. Namely a Clark's dash cover (nearly done) Sanding and re-painting my New Camaro Rallies and clanng and painting my Corsa Dash.

This leads me to a few questions I'v searched for and not gotten a definitive answer on:

PG in a Corsa Dash. I have the '89 Corsa Tech Guide detailing how to do it, but honestly left me a bit confused. Anyone here done it? tips, tricks or warnings?
My Corsa Dash does not have the fabled PG cut out markings they supposedly had.

225/50/15 tires on a 7" 1970-1981 15" Camaro Rally wheel. I've read again and again that 225/50/15's are great for the rears, but 205/50/15's are ideal on the front. Being frugal I've come across a great deal on 4 225's and I can't pass it up until I know that they will not work on a front of a LM to be lowered between 1.5-2" I've seen a handful of cars that DO run them on all fours and don't seem to have a problem

I had that exact combo on all fours on my '66. While the tires did fit (AFIR - it was 12 years ago), there were two problems. 1) with my 3.55 axle it was spinning 4-grand at 70 and 2) the front end really reacted to variations in the road -as in wild grabs to the left or right without warning. I swapped them out for 205-60-15 and never looked back. I did keep one for a spare 'cause it fits flat in the floor of the trunk.

I had 225's all around on my car all summer because I was using 8" wide rims. Lots of grip and they fit (with a little tiny bit of trimming on the front) but Craig is right about following road imperfections. I believe they also required more steering effort.

I took them off for winter because they were summer tires, but I think in the spring I'm going to put 205's on the front and switch to a set of 7" Camaro wheels too.

My New rims are actually 8" wide, not 7.


So for the Corsa Dash, I'll quote the section that has me lost. and hope for some help then.

Corsa Tech Supplement 1996
Power glide in a Corsa Dash- Milton Binion

" I take out the old panel, the Ash tray, and the Radio, and remove the shifter from the cable. A slot must be made in the panel using a 1/4" drill bit. The edge of the slot is 3/8" down from the sheet metal screw hole, and the slot is 2 1/2" long. I straighten out the top mounting of the shifter and cut part off. A piece of 3/8" square aluminum rod that is 1 1/4" long is fitted into the channel at the top of the panel opening. A #8-32 screw holds the top of the shifter. The bottom of the shifter is held on by a 2" strip of .040" aluminum. One of the #10-32 screws that hold the bottom mount can be seen below the ignition switch. There are holes in the bottom of the shifter that makes it easy"


I guess I'm stuck as to the exact placement of the slot for the PG handle. I notice that Milton does not say the slots distance from the right side of the Corsa Panel.

I vaguely remember that the Corsa dash has some imprinting on the back that shows the location of the slot. I'll take a look at one of mine tomorrow.

I've seen Spyder dashes with a PG cut out on the back, but never on a Corsa...

As stated mine does not have the imprint on the back.
Those that do, I'd REALLY appreciate some measurements.

Just a hunch here. I have never done the conversion but I saw it on a friends car. Her is what I would do if I were you. I am guessing you still have the Monza panel with the factory cutout. Why not just make a template from the old one and transfer it to the Corsa dash. I am looking at a picture of mine and the tachometer slot for the corsa is the same size and location on the Clock bezel on the Monza. You should be able to cut the slot in the exact same location.

What Cliff said.

205's on my Corsa still make it dart. I do have to say, I have never had an alignment done either. Something I am hoping to have done this year.

I don't have the measurement you need but maybe this picture I saved will help.

The Tech Guide says the entire PG bezel can't be used but it looks like it is in this install.

I have the Shifter out of the car and am seeing that the location in't a HUGE issue,(yet) Mounting is. The tech article to me is pretty vague in describing how to mount it.

"straighten out the top mounting of the shifter and cut part off. A piece of 3/8" square aluminum rod that is 1 1/4" long is fitted into the channel at the top of the panel opening. A #8-32 screw holds the top of the shifter"

What Channel at the top of the panel opening??

I'd give my right eye for a nice pic of it installed from the back.

I tried doing this mod, and could never get it to work right. The tach is too far to the right to even remotely fit the entire shifter bezel. The curve is way off. The shifter bezel would have to fit over the right trim of the tach quite a bit. I also tried removing the shifter slot in the bezel and fit the shifter through the indicator slot. It fit better but not perfect. All I can add is that I spent alot of time on it and eventually shelved the project due to frustration, and a ruined corsa dash

Now I'm determined winking smiley

Digging deep into any and all resources I have. I'll do this, and post an easy how-to. I promise you that!
