do you think a stereo system will add too much weight for racing or should it be ok?
Are you kidding!!!
First you want to know if exhaust tips would be good for a 9 sec 340 demon race car, then you drop to maybe a 10 sec race car, now your asking if a stereo would be good. What's up with this.
Peek into any 9-11 seconds race car and I doudt many if any will have stereo's. Who's going to be able to hear it for one and to build a 'serious' race car the last thing you worry about is 'tunes'.
No a stereo won't add to much weight to a race car....... If its runs 14.00's.
