A few points:
Those taillights aren't that bad. I don't think it will look right with the white car though.
I miss clear taillights. That said, I will be WINDOW TINTING My tails as soon as I get around to it (The black center trim I think inspired me). I will also be adding round fog lights, with angel rings, for reverse lights (And maybe changing the colors on the Angel ring, not sure yet - it's still half-baked)
I have a Feels wing in my basement. It's not worth the shipping.
For "body kit" I'm going with the garden edging. It worked wonders in the CRX. I need a lower lip for the rear bumper, and maybe a poly-plastic side trim. Something real sublime. Lemme know if you know the name of the style
The Trans: The 4 speed trans is the 91 HF trans without a top gear. That said, it's 4th gear is 100 rpm LOWER than the Si trans 5th gear. I can show you this. Each time you shift, the RPMS drop about 2000 rpm. Which means that you have to wind the stuffing out of it to make the next power band. If you learn that, then the 4 speed does just fine. I wouldn't trade it for the Si trans.
Also, You're doing it again
I wouldn't do this to a white car. I think the aftermarket lights will look like open sores on the back of the car. Clears, paint the lens red from yellow, or smoke them. Clears up front will complete that look.
If the car were black, or even blue (Although not my opinion) then these would look good, but I would say no.
