CPD004,

Are your lower links off set at the front like the 1st gen Camaro kit is?

If so you can switch to weld on brackets and flip your links so they offset to the inside which will move your lower mount inwards.

Albert, it definitely looks very different on my car than on yours. The rear was installed by a Ridetech recommended installer. I'll have to call them to see what they say.

Vince, I'm not sure what the first gen kit looks like. I'll take a pic and post what it looks like from the other side if that helps.

I've been dealing with the engine swap right now as I have no idea which direction to go with the rim selection. I'll have to eventually make some decisions though.

Hey Vince, I'm assuming your talking about the front mounting points of the lower arm? If you switch these how far inward does this place your mounting points? I'm looking to get a new shortened rear end built, but when I placed my wheels inside the wheel wells, one side was really close to the inner rim. I know there are slight adjustments that can be made to the front mount in order to align the axle, but I'm worried about how close it will be once final adjustments are made. If I decide to go with the weld-on brackets, how would I locate the point they needed to be welded given the wide tolerances built into older cars? This is going into a 69 Firebird.

I'm also trying to figure out the best way to locate my rims and determine the spacing to both the inner and out fenders. I'm running 325/30/19 Pilot Super Sports on Forgeline wheels 19 x 11.5 with a 5" BS. It looks like I have plenty of room with the 325's as I have a '69 I'm trying to move them out as close as I can to the outside fender to get the look I want, but I'm worried about rubbing during driving and also when I lay it out with AirRide setup. I don't want the top of the tires to rest on the inside fenders.

Last night we tried placing the wheels under the car but trying to get them to ride height was difficult, and then trying to measure WMS to WMS without moving them was FRUSTRATING!! So I downloaded this https://www.cachassisworks.com/Attac...structions.pdf and thought I would see if this would make things easier? I noticed that above the inside fender lip, the inner fender also comes in a bit which is what started to concern me.
