I have a stock rear 99SS with mostly bolt on mods and a QTP cutout on an otherwise stock exhaust.

I may have a chance to get an ST3500 converter at an excellent price but don't know how this will effect driveability---the car is a daily driver mixed with some weekend street competition.

Any opinions are appreciated.

 

Go for it!!

I just got my TCI-3500 installed yesterday, very drivable.

I am stock as well.

I'm assuming you have a 3.23 diff. My 2.73 with the ST3500 is a little "loose" around town, but kicks major butt-no problem for me with the increased performance. Only thing you may need to do otherwise is get stickier tires, 'cause this TC will light 'em up.

i have an st-4000 and it is on the ragged edge of a comfortable daily driver. after it locks up, it is perfect. the 3500 would be perfect honestly. go for it. it hits HARD <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
