2.4 VS LNF for Auto-X

So currently I own a 2009 Cobalt LNF and have taken it to a test&tune and 1 auto-x event. What I quickly realized is that I have negative headroom.......sadly i have forced to have the sunroof open just so i can fit my helmet on, even then my head isn't straight. So my solution is to buy a Solstice Coupe ASAP so I can remove the top for each auto-x event and have unlimited headroom. Now, owning the LNF currently i'd really be disappointed with a 2.4L but I might not be able to afford the LNF Coupe. Is the 2.4L still 50/50 weight? Same brakes? Suspension? Seats? Am I far better off finding a way to afford the LNF GXP Coupe?

suspension is bit different from 2.0 to 2.4.brakes are the same, differnt stiching on the seats. if you can find a gxp w/ the zok package would be better as it different springs/shocks and larget stiffer crossmember in the rear, bit lower too. if you could go for the gxp..if you already have an lnf you'd be dissapointed b the 2.4 unless you boost it. sure others will get more specific and technical w/ the differences.

Talk to a salesman. They can probably order you a Z0K LNF coupe.

2.4l roadster with a supercharger and suspension/brake mods would be something that I would explore. Might make some sense cost wise.

The coupe also has less headroom than the convertible, try to sit in one first even without a helmet.

importanat questions:
do you want to be competitive (local or national level)?
are you going to want to modify it?

If you want to be competitive either the 2.4l or the LNF should be good in a convertible. not sure on the Coupe's weight (more or less than the convertible?).

If you want to modify it and stay competitive i'd stick with the GXP. you'll go into BSP and can be very competitive localy and nationaly it's still up in the air (it'll probably be an uphill battle).
The 2.4 will go into CSP and will probably get smoked by miatas.

Now if this possible Street Touring class for larger 2 seaters evolves then i might think about the 2.4L.

If you don't care about being competitive then any choise will be a blast!

I don't know where you got that info, but the coupe is reported to have more headroom. I have sat in both, my head touched the vert fabric roof but in the coupe I had a couple inches of space above.

Gm posted interior specs when they released the coupe info, comparing it to the convertible showed it had less headroom. But if you sat in both and saw more room in the coupe then i guess someone messed up the original numbers.

Or the seat wasn't all the way down.

To the original poster ... our base Solstice is nicknamed Annie ... short for anemic .... while she's a wonderful dance partner for autoX causing any sort of excitement when the right pedal is pressed isn't her forté. Why not get a used GXP roadster if $$$ for the GXP is an issue?

I absolutely want to be compete on the national level when I've tuned my driver mod to an acceptable level. I had planned to stick with stock class on street tires for the Cobalt and would want to do the same for the Solstice. I had picked Kuhmo XS for my tires just hadn't been able to order them yet which is good cause I'll want wider rear tires on the solstice. From what I understand a few Solstice Coupes have made it to Canada which means one should arrive in my City shortly for me to try and acquire.

I won't drive a convertible in a Calgary winter........just not a good idea, i'd like to acquire a GXP Coupe, that is my goal right now.

If you want to be competitive in autocross with a solstice go with the GXP with the new tune. I have a 2.4L that I ran in C stock last year and even as a rookie I fared well against the local competition. Had several 1st and 2nd places in class and made it to the top ten at the end of the year in PAX. I modded the car (not for autocross purposes, but just because I wanted to) with the stage II Supercharger and new shocks, springs and anti-roll bars and brake pads. I now have to compete in SSM. Although I am placing well as far as RAW time is concerned (within two seconds of the fastest car...I compete with street tires by the way)...I get killed in the standings when it comes to PAX. Now if I switched to race tires, it could mean a big difference but for now my budget doesn't permit it. So if you are looking to get a solstice and want to be competitive in the standings, then definitely the GXP would be the better choice.

my goal is the solstice gxp coupe this summer and next summer get a GM intake kit and tune and some type of custom exhaust to match up with some R-comp tires.

If you want to be competitive (especially at a higher level), get the coupe and do not get the intake and tune. Those mods will move you into a higher class where budget counts as much as driving ability.
