Introduction / Looking for advice
I’m a huge gear head, sports car enthusiast, shad tree mechanic and a want-to-be racer. I’m in my late 20s and I’m in the military
. I’m about to buy a used corvette this weekend. I wanted to ask the vette community if an LS3 Coupe is going to suits my needs. Sorry about this being long.I’m trading in a 2012 Evo X GSR which I thought I was going to love, modify, track and have for years… I can’t stand the car. It has an identity crises and is really cheap feeling for an almost 40K car. As for modifying a small displacement insanely high boost engine is risky to say the least. I’m a military pilot and I don’t have time to risk a blown motor. As for tracking, I was only able to autocross it a few times, but I’m planning on competing in at least a dozen events this season. I’m very inexperienced as I've only ever done half a dozen HPDE, but I do have a little talent and with practice I believe I could be competitive. The Evo X is a great track car that is extremely tight and precise but it was a fling that I’m over now.
I grew up with a corvette in my parent’s garage and lucky for me (not my dad) my parents worked a schedule that allowed me to sneak the Vette out frequently. So from the age of 8 through my High school days the Vette was always something I loved. I’m looking into a 2012 6spd 2LT Coupe. I really wanted the Z51 but I don’t want to get an older car without warranty (otherwise Id just get a C5z) and I don’t want to get a GS as I can’t afford the 6-12 grand over a coupe. Basically I can get into a low low mile 2012 for the same payments as my Evo. Oddly my insurance premium is lower and annual fuel cost will go down.
Before buying the EVO X the community warned me about cars about quality issues and just how generally difficult ownership was. The EVO is fragile cosmetically. I had a hell of a time keeping this car pristine. The paint is extremely thin and easy to chip, the doors dent easy, the leather steering wheel crack in cold temps and Mitsubishi warranty is a JOKE! Mechanically, oil changes every 3000 miles and the factory clutch is extremely weak. A lot of new owners who launched their new car destroyed their factory clutch in less than a few launches. I just want an enthusiast car that in stock form I could run hard and no worry about. I also want a car that’s cosmetically robust.
So will the LS3 coupe have power, handling and precision to be competitive in the SS class in autocross and will it holdup to some occasional track days? Will the car take a licking and keep on ticking?
OR
Am I just setting my expectations too high for a C6 Coupe?

If you are indeed planning to have organized racing... throw out the idea of being kept in pristine condition. Corvettes end up getting painter's tape all over it.... since fiberglass is softer than metal body panels. If you are planning to finance the car - you will need to increase the budget regardless the make... due to unforeseen breakage during stressing moments.
The LS3 is a strong base motor - with plenty of bolt-on options... however as you noticed, a Grand Sport is better equipped with a better suspension, tires, and an oil sump pump.

I really really wish I had the extra income to just get a GrandSport and honestly in a few years when I have more disposable income Ill probably wish I had bought a GS. Yet since I plan on tracking the car the consumable will be cheaper as the Coupes tires are smaller (still not cheap) and the brakes are rather basic.
I can always put on a sway bar and some Koni Reds and remain in the Stock class for SCCA.





for that reason(s), I suggest you ask and post in the autocross section of CF. and read up on it there as well. as to getting the car before you do this homework, that's your decision altho it wouldn't be what I do.

I think the LS3 will be a great track car for you. I tracked my base 06 LS2 and ended up putting the widebody, bigger brakes and engine mods, tranny cooler, etc. I have the Z51 option too.
The Vettes are easy to work on, parts are easy to come by, and it is a great base to build up as you grow into the sport. You can easily add as finances allow.

I've added a picture of the exhaust which doesn't look stock and I was wondering if someone could educate me on it.
The Best of Corvette for Corvette Enthusiasts
If you are going to track the car, I also suggest the GS. It's already got what you need.
Other forum members quote 30+ MPG, I get around 25 on the highway running around 80mph. The cars seem durable and many have well over 100K miles on them.
The C6 does have a few quirks including a clutch that needs regular attention (fluid swaps).
Good luck and thank you for your service!

Ill see if I can dig up the link where I found them.

My dad has a C7 Z51, Mag shocks, NNP and 3LT. It's the blue premium car that is limited. It's sick.

mcandrew just about sums up my thoughts. I track my '07 Z51 coupe and do lots of mods both performance and appearance... I do about 6-8 DE days per year and I attend many car shows and club events. It's truly a dual use car that I get as much seat time in as possible. I think the LS3 is THE BEST track base engine in these cars.
(yes, I have an LS2 which is also great, but why not take a few more ponies).... You can go the bolt on/tune route and just keep up on fluids, pads and incremental improvements to brakes, seats, etc as you gain seat time.. The car has way more power than you can use on most tracks or any autoX.. it's all about the driver!... lower lap time= seat time and bigger ba_ls.... Oh yeah.. some R compound rubber after a few DE days will make a HUGE difference as well!... Buy the car and enjoy!!.. and let the moding begin. (It never ends)...

IMO the Vette is the better car in every department other than the handling. That might change next week I have a new Bilstein setup going in on the Vette.
The Evo X has a custom turbo putting out around 500awhp. It's a beast but you really have to put it in the power band to keep the turbo spooling.
Vette is easier to daily drive, gets better fuel economy, and overall is my go-to car.
Happy hunting let us know if you have any further questions...
