The Stock Car Classification Guide puts the 90 convertible LX at 3168 and the GT at 3197 shipping weight. 302/225, right?

I've been using the stats here on the forum... http://www.classracerinfo.com/Default.aspx

Let me go check the NHRA site for changes...

Edit - It appears there was a hp hit across the board for the 302 (225hp). Whats confusing now is the weight is greater for the '89 than for the '90...was reversed.
'89 - 3394 pounds
'90 - 3312 pounds

I guess it was because the '89 gained 10hp from 215 whereas the '90 only gained 5hp from 220.

Lol...this is all wrong dammit...there were no changes for Stock.

Looks like a fun project, good luck. You might want to contact a friend of mine who is on this forum. He has a 89 mustang convertible that he runs in P/SA. He also has a 92 lx coupe that he runs in SS/MA. The stocker is usually around the .500 under mark and he does it on a budget. His user name is fordteacherguy and his real name is Brian Thompson. PM him and he will help anyway he can. Brian is very knowledgeable and a very nice guy to talk with. Can probably give you some advise to help save money. Good luck.

If you are going to put subframe connectors in that are worth putting in, they need to be through the floor. Not under the car, especially a convertible. These cars flex a lot with a full roof. You may want to search the forum, as there has been a lot of advice on rear suspension and how to fix and support it too.

I figure a roll bar will help with chassis twist/flex as well, but I'm open to all suggestions. Keep in mind the intended class and likely power level. I have searched the forum but came up with little detailed info on these cars. I have found some useful info on Corral.net tho. Does anyone know what the exterior differences are between a '89 and a '90 GT convertible?

When I started working on my 68 coupe, I could jack the right front torque box and just lift the right front wheel. Now with a full cage, weld in sub frame connectors and a bolt in x brace, the same jack point lifts the whole right side of the car. Stiff as a board. The connectors aren't through the floor, either.

Do a google search on "Mustang roll cage" and click the Images tab. you will find a lot of builds that include connectors both under and through the floor.

99.9% sure that they were the same. Except for the switch to the bigger brakes/ 16" Pony wheels in 1991 I believe the styling remained the same.
