Hi,
Yeah OK, I don't need much arm twisting
As the lucky owner of this gorgeous seat, I wouldn't say I've had it a long time - but I have racked up thousands of 'miles' in it.
The seating position was really important to me and the 8K2S allows the authentic feel of a motorsport formula or prototype seat. The seat back is 45 degrees and as a result is very comfortably reclined so much so, you could probably go to sleep in it! Even having a 32" waist, the seat is very narrow and a snug fit - but again is authentic and I really like it. There is a wide version of the seat which I would suggest is more sensible if you are any larger.
The double skin model has side mount points, allowing easy bracket attachment to profile, or in my case a seat slider. Being fibreglass, there is a bit of flex in the seat under heavy breaking - perhaps 1" on the backrest? I don't see that as a problem as fibreglass is flexible but personally would have concerns about the durability of the fitting through the arm rests on the single skin version - there is a disclaimer from Luso regarding load cell pedals not being advisable, probably for good reason.
The customisation of the seats is really cool. Any RAL colour, different pad and stitching options, and plenty of other tweaks. I've seen some really nice examples on the Luso FB page, and options are really limited only by your imagination. The owner - Ernesto was open to pretty much anything you wanted. One thing that I would have specified if I'd know was an option was the side cutouts for a 4 point belt. I suspect Ernesto would add a 5th point cutout if you wanted. Without any cutouts however seat belts are not an option. Bare that in mind if you have plans to add them down the line.
I did look at the SIM Lab SF1, Sparco formula and even the forthcoming Luso 9KS SIM seats. All look good options tbh, but I still think the 8KS would provide the most realistic experience due to the body clasping width and side support. Those side supports do make getting in and out quite tricky - but, you know, its all part of the experience! The other seats are a bit over padded for me. TBH I would have gone without any padding, but thanks to a previous post suggesting it gets sweaty without them, I optioned the pads - with fetching Bentley-style diamond stitching. Glad I did as they are comfortable and look great. I requested no leg-side pads as I thought they seemed unnecessary. Sliding in an out of the seat - I'm glad I did as they would probably just have got in the way.
Price wise, the seats are good value though the custom options will pump it up. Shipping was quite expensive to UK but well packaged in one of the biggest cardboard boxes I've ever seen. I guess you also may have duty to add now.
Rig-wise, I'm using a modified P1X and couldn't be happier with it. The 8KS slots in very nicely indeed.
So in summary: Great finish and quality, very comfortable and good value.
Highly recommended.
