The stock beams is good to fight with Type-R´s, GTI´s, Focus ST´s and other hot hatches. I rahter invest that money to:
- Suspension upgrade
- Good stiff and light anti sway bars
- Ultralight wheels
- Lighten the whole car (fibre bonnet, trunk lid, front wings; Aluminum radiator, AC delete, lighter manual seats, sound deadening removal etc)
- Good exhaust system
Then you car will take corners perfectly and will accelerate 0-100 less than 7 seconds.
I would change my IS300 2JZ to good RS200 any time. IS300 is heavy beast compared to RS200Z. Although it is easy to add turbo to 2JZ and make this an quick car on straights.
Problem is that there is basically no LHD RS200 available....
