Hello All,

I previously owned an 06 SS/SC with the G85 seats and LSD. I sold it when winter came, and I am thinking about building a Stage 2/3 2007 Cobalt SS with cooling mods and sending the blower out to get ported. Looking at around 275 hp.

The question is: I am looking at a 07 SS withOUT G85, which means no LSD. I dont plan on driving in the snow, but I am wondering if the difference when driving spirited in turns will be noticeable without it, or if off the line acceleration and traction will be hurt by not having it and stage 2/3 mods. Ive did a search here and some people say its not necessary while others say its mandatory.

Given the application, should I just look for another SS with it, or will I hardly notice the difference?

 

A lot of people say that you wont notice the LSD when you just do normal driving, even spirited. it really comes in handy when you track the car.

However, being that Cobalts are sort of rare find (around here at least) I wouldn't not buy one you find cause it doesnt come with LSD.

 

It's not "necessary," but it does help. My turbo swapped LSJ does not have LSD and it does just fine. When I get a new tranny (aka: soon), I'll get one with the LSD though.

 

even with the stock power, the open diff can be a bit of a let down on corner exits.

if it bugs you that much, replacing the transmission isnt that hard. im just gonna beat the **** out of the one I have and replace it with an LSD trans when it finially gives lol.

If you are a good driver, there won't be much difference if any in the 1/4.

if you are letting the wheels spin a lot, then your 1/4 times would benefit from the LSD most likely.

driving with an open diff on a course can be a challenge, but it teaches you throttle modulation a lot more than the LSD setup would, so that is one advantage of it if you are looking to improve your driving skills.

 

for straight line traction you will do ok, 1st gear is useless but thats to be expected, guys regret not having LSD in LNFs over 20psi, so 300+ is what ive seen have traction issues.

 

Cornering is the only time that you will notice a difference. If you plan on autoxing then you need one or even road racing. I have an open diff and autoxing totally sucks but road racing isn't as bad.

 

I know this might sound like I know absolutely nothing about cars but this is my first fwd. That being said, how is there a difference between making a corner or wot lane change with or without a limited slip?

Thanks!

 

The tighter the corner the more you notice the difference. Really tight corners without a diff the inside tire will spin easily and the car will not go anywhere until you get more weight on that side. Lane changes you really wont notice a difference.

 

I see. Thanks!

 

You will certainly notice it in the turns, lots of wheel spin when accelerating while turning. I got it all the time in my SS, but I managed. It's fine without in a straight line. My LNF made 300/360 with no lsd.

 

^ this. I have no lsd and mine is fine straight line and easy corner acceleration. shouldn't be going around hard corners flooring it on the streets, if it's track or autox use that's a different story.

 

roll racing/drag strip is were its at lol, gotta get that 1/4 or feel 150 plus on the interstate or out of town roads

in mexico of course..................... :P

 

Thanks guys, I pulled the plug and bought it. ill have a new post up soon.

 

oh btw i drive mine in the snow. with some snow tires, it is a beast.
