Not 100% what you're asking for, but I think you'll be interested:
https://www.chevrolet.com/camaro-spo...r/1le-packages

Differences I can think of:
Smaller, but wider tires
Sticker 3R tires
Multimatic dssv shocks
Hard mounted suspension
Aero
10 speed auto has a unique track tune
A bit more air flow through the front

there is another thread on this - but I was not able to find it.
A different guy wanted to modify his to 1LE specs, but its not worth it.
The end synopsys was that it was cheaper to just buy the car.
a very small amount of it is listed in the GMPP catolog:
https://rj-conlin.dcatalog.com/v/202...atalog/?page=1


front grille w/ canards & front splitter, fog lights removed.
rear spoiler (and allegedly truck lid)
wheels / tires
multimatic DSSV coil-overs (no mag ride)
lower control arms
sway bars
cradle bushings
rear suspension parts
PTM mode algorithms
Manual transmission is close ratio w/ no overdrive

i know its cheaper to buy a 1le but its almost impossible to find one in sweden and a want to have all the chassi parts on my zl1, so it would be nice if i could se the oem parts nr on all the parts..

Thanks for the gm catalog it will help me

Cradle bushings and wheels/tires would get you most of the handling improvement with reasonable cost.

You're saying the cradle bushings and tires get you 60-70% there without the DSSVs?

If you're asking how a non-ZLE achieves a similar level of handling on track as the ZLE then you're already putting on track tires--SC 3Rs, Hoosiers, etc. The DSSVs are a much bigger part of the ZLE's 1.1+ G performance than cradle bushings, they're unique world-class suspension parts that give the car most of it's uncanny grip and sharp feel, together with the sways. Cradle bushing help, and the aero helps a lot at speed.

I had some excellent KW V3 Clubsports on my Evo X and was putting down fast laps, the day I switched to Ohlins R/Ts I gained nearly 2 seconds--all other parts identical.

The DSSVs are truly remarkable and add a lot of performance to the ZLE (love them on mine). However the extra cost to add them vs return on investment for MOST people is not there. The cradle bushings and tires are easily added and not too expensive for the return on performance.

If you’re willing to get DSSVs, new bumper, dive planes, wing, PTM tuning, M6 with lower 6th gear, etc, may as well just get an actual ZLE. In my mind, adding DSSVs are a tipping point where it makes more sense to just get a new car from a coat perspective.

I agree, I'm not suggesting anyone convert a non-ZLE. As a ZLE owner I would also never swap out my DSSVs for custom 3/4-way adjustable Ohlins even though the performance and front/rear height adjustment would be better. This car with what it came with is all I need, I have a long way to go before I exceed it's exotic car beating capabilities

The differences are this (compared to ZL1 coupe):

Body
-Black-wrapped hood and blacked-out mirrors
-Slightly larger front spoiler
-Front fascia-mounted wheel/tire aero diverters
-Pratt-Miller/GM designed rear wing

Suspension
-Multimatic DSSV dampers
-Front radius arm is a different P/N (different bushing design)
-Rear knuckle/upright is a different P/N (higher durometer bushings)
-Rear cradle has solid metal bushings (in place of rubber)

Wheels/Tires
-305/325 (F/R) GY Supercar 3R tires (near R-compound tires)
-19x11/19x12 (F/R) wheels

Miscellaneous
-Revised calibrations for the track and to accommodate component aero/suspension and tires changes


My suggestion is to start with wheels and tires, the solid-metal rear cradle bushings, fill up on your fluids of choice and brake pads of choice and go at it. Maybe add the aero.

thanks everyone

Who can reprogram PTM?

If you get a 10spd Auto car, that eliminates the Trans item.

Just not familiar with PTM mod?

Best regards,
