B Pillar Harness Bar & Wheels Issue

The current racing harness arrangement needs to be re-worked. While it is functional enough, it creates inconvenience for the rear passengers as well as limiting the load carrying capacity when the rear seat needs to be folded down. It can always be disconnected but that creates a safety issue. The B pillar harness bar is the simple solution to the problem. I remembered seeing it on my friends' WRX and thought it was a very good idea. Not only does it create the support for the harness, it also provides some strengthening to the chassis. Coupled with the existing chassis bar, the B pillar harness bar will do wonders to the overall integrity of the car. Here are pictures of how it looks like.

The search for a lightweight set of 18" set wheels has probably ended. Just a quick recap on the various options I was considering and in fact, almost committed to buying but nonetheless, the deal did not go through for whatever reasons. It started with the G07 Motorsports, same design as the present set but in 18" guise and white in colour. Decided against it because while it is strong, it also has a hefty weight issue and I am also not sure about the white wheels. Next, the Magline HF601. This is a good set of forged rims that was quite light but somehow the seller never reverted despite many reminders. So, I decided to drop the chase. Finally, the wheels that would most likely make it to the car are Advanti Vigoroso Nebullar N993. The specifications are close to what I am looking for; 18 x 7.5JJ, offset 45. These wheels are made with MAT (Most Advance Technology) licensed by Enkei. They weigh about 7kg per piece, which is about the same weight as the OZ Superleggeras. They look neat and simple, in fact, much like the 19" Tecnomagnesium on Daisy. So, I figured if big sister has them, little brother should have the same design too. I would much prefer the silver ones but the distributor brings in only the matt black and bronze. Here are the pictures.
