With your kitted, sub pumping, custom plate wearing black R34 on P plates you will cop it HARD.
I had all of the above in my S15 with P plates, and got defect after defect, its not fun at all.
The things i found to make a differnce are in this order:
1. P plates, these are like red rags to a bull, I have had police admit that they pull over modified p platers above all else.
2. Noise, the less you make the better (exhaust, system, ect)
3. When/where you drive, Chapel, Knox FTL!
4. How you drive.
