I can attest to that too I've spent roughly $4000 on my car aftermarket and it's starting to open a few eyes on the track. Last time out I put an ST185 celica to shame. I was holding off a series 6 RX7 and passed a series 4 RX7 down the straight. With another ~$4000 to be put into track tyres, brakes, clutch, flywheel and LSD there's still plenty of potential there too ;) I'm predicing at least a 1:13 around Wakfield Park when that is done :D It doesn't take much to be spent, it just needs to be spent in the right places ;)
