Let's see. There are plenty of customization options for this car.
1. Vinyl wraps -cheap and easy (latter being up to you). You are only limited by your imagination. If you need help I have a bit of knowledge in this area. It's very easy to go overboard with this stuff though, but it's up to you, do what you like and care less about what others think
2. Diffuser - About $800 from Difflow. I love them and they are both functional and good looking.
3. Dead pedals - Sector 111 sells one for about $70, or you can order a factory one straight from Lotus now that looks a hell of a lot better.
4. Front splitter - There was a small batch of them that were sold earlier this year but they were all custom made by Bobsy Racer. No word on whether he intends to make any more. I think he sold them in the $500-600, maybe more. Or you can make one yourself. He did.
5. On the expensive side of things, you have many options, both from Mansory and from Lotus Sport (GTN upgrade kits). I have the GTN louvered rear glass replacement cover that originally came from VSI Motors. I believe they sell other GTN parts. Anyway the other parts available for this car are:
a. front and rear bumper kits
b. Bargeboards and side skirts
c. Side vent scoops (two different versions)
d. Rear sail panel (the vent cover above the rear lid)
e. cf rear diffuser holder
d. cf rear diffuser
f. cf rear lid replacement
g. plenty of Lotus wheel options
h. cf doors and plexiglass windows
i. rear spoilers (2 different versions)
j. cf vented side panel
k. side mirror covers
l. cf a-pillar covers
Come to think of it I think the entire GTN body kit is all CF.. will run you upwards of $40k-50K I think.
Then there are some goodies from at least one European shop (I don't remember them so you'll have to search the posts, I know I mentioned them before), such as a CF intake kit.
Also there is the CF lithium battery kit from Chimera that's very nice. And a few owners have also had custom interior work done-- headliner, car seats, etc..
... that's all I can think of for now.
Ramtin's car is one of a kind. There are no rules on what people should and shouldn't do with their cars. Everyone has an opinion. What matters most is your own.
