If it was standard and just had the stripes on and nothing else then i would think it was okay, but even without the stripes it would be better. everything else is just a waste
If you've spent near to £2,000 on tinting windows, stripes, an IK, lexus lights, exhaust, bee sting aerial, then i'm afraid to say that you've been short changed.
And there is no way in hell that you would be pushing 185bhp from an IK and exhaust. An IK may (key word MAY) give you 1-2bhp on a COLD day if that. exhaust again maybe between 2-5bhp, nowhere near the 13bhp you've claimed.
okay i know that its a slating but to say all these things about your car and pull a dozen tongue smilies seems rude to me. if you hadn't have done all the tongue smilies then i wouldnt have said anything, but it pissed me off frankly
