It is hollow, and the whiteline is solid, so it isn't actually too much bigger. It is a bit lighter though. Probably 10-20% stiffer and 10-20% lighter. But, it isn't adjustable and the fitment isn't as good as the whiteline. -- Brian
I must be behind the times. Last I heard Brian got the CRX. When did he trade the s2000 in for an EVO?
Mere told me that the s2000 was too much of a girly car, and convinced me to sell it and get an evo. I have had it since the end of october. Put a Perrin catback in the STi today, and it sounds pretty good. http://mere.darg.net/sti-perrin-catback -- Brian
This bar is quite good. After using it for a while, I can tell that it is quite a bit stiffer than the whiteline bar. The front feels quite a bit stiffer and stays planted better. This makes it much easier to whip the car around and get some oversteer action, Turn-in feels much quicker. Highly recommended if you are planning on autocrossing. -- Brian
