The only urgent improvement that I would like to make to my 4c LE is that I would like to stay in place when using the full capabilities of the car.
My Lotus Exige came with a harness bar and got a kit to install 4 point although I prefer 5 or 6 point.
Any experience on this issue?

No harness bars that I know of yet. They'll be a tight fit for guys tall enough to need to keep the seat all the way back.

If it's for street use, have you considered a CG Lock? http://www.cg-lock.com. They work great and are easier to deal with than a full set of harnesses. You can still lean forward when stopped, etc. They're safer too, unless you use a Schroth 4-point with ASM.

JWA, I am thinking more along the lines of track. In the Lotus I had the Schroth and liked it. My preference would be 5 or 6 point but need to modify or change the seats. The Schroth 4-point is not acceptable to the Porsche Club and other organizations (even ASM) , they consider the OEM safer-go figure

I'm pretty much in the same wishlist.. and no, i havn't found a solution yet... the only oone i've found is a swiss company that has a 4 point harness offer, but i have to check with them... i do not speak or undertstand german, an i would like some details on how the job is done.. i've heard people saying "no problem, just drill a couple of additional holes and put the plates to fix the new harness points" this thing work pretty fine on a metal chassing, drilling a carbon fiber monocoque once is cooked is a no-no IMHO...
BTW the company i've found with the 4 point harness offer is:
http://www.straeulimotorsport.ch/

Please note that most probably in several countries such installation would not be road legal, as the original 3 points harnesses cannot be kept and used...

5 and 6 point.. seats are an not an issue, you do have to change the original ones anyway, they cannot fit even a 4 point harness as they do not have the proper holes... i'm more worried about the additional installation points needed to fix the additional strap..

For non-professional use, but just to be tightened more to the seat the suggested cg-lock lock is a good choice (and much safer than a non properly done 4/5/6 harnesses installation..)

Ricky1750, I do not want to offend anybody with my references to my now gone Lotus Exige but that is what the 4c replaced.
For the Exige, I had 4-point harnesses installed but left the OEMs in place. Occasionally, I would run the Lotus with the Porsche Club and that is how I learned that they consider the OEM safer than the Schroth 4-Point ASM

You're not offending anyone.. i'm perfectly aware that the OEM 3 point are safer than 4 points unless the 4 points are propery installed... the cg-lock blocks the oem so that you have most of the "fix" the 4 points harness give and all the safe of an oem... the 5/6 point would be ideal for avoiding submarining, but i do not see how it would be easily possible on the 4C :frown2:

Roll bar another avenue

I have only had the 4c for less than a month. Have not seen any roll bars for this Alfa. But even at that, the hole through the seat for the 5/6-point harness remains an issue. I actually like the seats.
