does the 2003 g35 automatic have a LSD? or is it a pegleg

 

peglegg!!
The ATS looks like an awesome replacement.
I have the KAAZ, it works great.

 

i think you get lsd if you bought the car with the performance wheel and tire package...so if your car came off the lot with 17's then you don't have lsd

 

I have an '03 AT G coupe with LSD - it did come as part of the wheel/performance package (a great deal for 600 bucks - 18" wheels with Michelin Pilot Sports, the LSD, and the 'titanium' trim on the dash.)

The LSD is a viscous type, not a mechanical 'clutch-driven' LSD though. The MT coupes from that year (and every MT coupe since then) also has viscous LSD.

However if an '03 AT coupe came without the Wheel/Performance package - yep, it's going to pegleg!
