They don't seem very expensive, and if they, based on the replies I get here, seem like they'll help my car towards my ends I will surely get them... as in my other threads, I am looking to build a car that can handle while remaining as fast as possible with a big engine in the straight line.. would export braces/and or monte carlo bars stiffen the body too much for weight transfer (though I could take them off at the track) or would they be good for overall handling?
