If you go with any of those kits, go with the Ridox with carbon fiber trim. It will look excellent on a red car. If you want to see many different pictures of that kit installed, let me know as I was going to go that route with my Supra, and did plenty of picture collecting.
In the end, I decided to stay stock bodied though, so I am selling the bumper I already had (Modellista Designs Type RX - the Ridox clone they made). Let me know if you want to check it out to get an idea of what it looks like in person or anything.

I like the 4th one. I love the stock lines of the Supra and the first one just seems too over the top. I've been considering a Stillen bumper for mine, thats the only body work besides paint I have planned.
