So I have about $500 to spend on my car this winter. Any suggestions on what I should do? Or should I wait until I get a little bit more money to do somethings?
What do you think?

What do you think?

stiffen up that vert chassis for sure! subframe connectors and some upper and lower control arms!
I had a buddy that went to long without them, and once his car got to running about 300 HP, he cracked his windshield launching on drag radials.
That's pretty bad ass.
200$ is a lot!, I thought it'd be cheaper than that.
never taking my car to them again! sorry for the ramble, that just got me mad again...

That's because it is cheaper than that. Somebody must have saw that other guy coming. Before I took mine to a shop I loosely bolted up the subs and grinded where the welds would be needed. Then I tightened up the bolts and drove the car into the shop. They charged me $60 to weld them up.
First off, the shop needs to have a hoist you can drive onto that lifts the car from under the tires. This will prevent the chassis from twisting before installing them. Secondly the shop needs to have a mig welder.
When shopping for subs, since you have a convertible, look past the standard length connectors and go straight for the full length subframe connectors.
That's all I have to say about subframe connectors.
Is your car a daily driver? If not, my guess is you don't plan to put many miles, if any, on it this winter. So throw on a cat-back exhaust and maybe some unequal length shorty headers if you have any money left over and do the subframe connectors this spring.
