LT1 Lowering Consideration
I read a number of posts on lowering Camaros of different flavors but didn't find anything about doing so on an LT1. I'm understanding the LT1 uses the same suspension and setup as an SS, but not certain about what differences there might be. I'm riding on 1LE wheels with Goodyear PS3s in 1LE sizes.
Any thoughts?

So I recently put 1LE spec wheels (MRR 017) on my 2SS (with MRC), I was going to lower it, but after looking at a slight bit of "poke" on my front wheels, I don't think I'm going to risk it because I think I am going to possibly have some rubbing issues and I do NOT want to risk that...

RST PX1 1.5" lowering springs on 2023 LT1. First picture is before and after with 20x8.5" squared stocks. Next pictures are with drag setup. I have a set of MT 305/35/20 mounted on another set of stock 20x9.5 (I know it's too wide for a 9.5"). These aren't ILE size or offsets but I think you'd still be able to clear it. I'm going to try it as soon as I find something in 1LE specs. Harness has already been relocated if anyone is going to ask.

To the OP: I though the LT1 came with taller and softer springs and bars than the SS, but it will have the same suspension geometry. In fact, it will have the same geometry as the SS 1LE, too. So you can do the same lowering as they can. Since you don't have MRC dampers, it should be even easier. My concern with lowering these cars is that most of the aftermarket spring sets available now don't have significantly higher spring rates than a stock 1LE. When you lower a car, it sits closer to its compression travel limit, and that means it's easier to bottom out on the stops if the spring rate isn't increased. That's neither comfortable nor good for handling. In your case, though, they probably are all stiffer than your stock LT1 springs. It occurs to me that the cheapest and maybe easiest way to lower your car with an appropriately higher spring rate might be to just buy a set of SS 1LE springs. My only question is because the 1LE has MRC dampers: does anyone know if those spring diameters and spring ends are the same, so that they can interchange?

I'm just worried a little bit about this front tire "poke" after putting on the MRR 017 1LE Replicas (technically the fronts are a +23 offset (vs. the OEM 1LE wheels with a +20 offset) so my wheels/tires SHOULD be 3mm inboard more (less poke), I just don't want to risk any rubbing...

Of course the SS 1LE does have different more performance track oriented suspension than either stock SS or LT1 so I assume your comments do apply vs SS 1LE springs.

I don't know the difference in ride height between the FE3 and FE4 suspensions, but I do believe the FE4 rides lower. I have seen at least one post that says the LT1 Camaro came with FE3. If so, then yes, it's the same as the SS.

Ok - Great info, thanks.
And yes, I confirmed my 2023 LT1 has FE3 Sport Suspension RPO code on the printout my dealer gave me so is same as the base SS.

I could but I don't want to wear out the inside of the tires too fast, I don't track so don't need a lot of camber... I may just throw the Eibach springs in when my brother comes out to visit and see how it looks... I just really do not wan ANY rubbing issues, I just want to close in some of the excessive wheel gap...
