what is the largest aftermarket seats put into a 308/328 or 348

I haven't seen an EVO 3, but I've seen the EVO and EVO 2, and I'm surprised you find those more comfortable than stock seats, since the EVOs have quite a "butt bucket" design.

 

If you go to this thread
www.ferrarichat.com/forum/showthread.php?t=62867
you'll see pictures of 308's (same seat arrangements as the 328) with Sparco seats.

 

It's a 308/328 ENGINE, but the chassis is different.

 

You are correct about the EVO 3's... they're four inches wider in the inside seat/butt area than the EVO, and three inches wider than the EVO 2's.

You can see all the Sparco seat specs at www.sparcousa.com/resourceFiles/26.pdf and look for the "Z" dimension.

 

These look nice # SUM-G1155B and they come in tan:

I'm as big as you are and have tons of room in the Mondial - it is an amazing and underappreciated piece of engineering packaging.

 

I have made my own fixed back racing seats. I will also be making a reclining and tilting version for my Mondial Z project. I will measure them but I know that I made them wider than the Sparco Evo.

 

Hi, the car in the link with the black Roadster seats is mine. The problem is width. The 308 offers little width and on the innermost section of the car with the Roadsters mounted you JUST BARELY have the seat fit. In fact i find it is best to begin building/mounting the seat in sections into the car. Think i documented it somewhere here on Fchat.

SIDE NOTE: i am going to try reversing the brackets with the bottom chassis bolts from now being towards the inside of the seat to being on the outside of the seat. This is a FUTURE project in a month or so.

The Roadster will <cough> comfortably fit upwards of 36-inch waist. i am a 32-inch waist and fit fine. (Humor) You could say it keeps fat chicks from trying to sit in the car

Looking at the Evo specs i think you will have problems. As for further back, i am nearly 6' and have 32-inch legs. With the Roadsters mounted on the OMP HC730 low model, you have PLENTY of room to mount the seat far away from the steering wheel. In fact i am going to be mounting a Sparco steering wheel release, this will bring it closer to me by about 3 inches. As for the seat bracket, the HC730 is 400 mm long and what i used. Guess if you wanted to go even further back you could get the OMP HC832 as it is 495mm long.

NOTE: For any side bracket with the Roadster seats you may need to cut the top of the front of the bracket to get the seats to mount as low as possible. The problem is there is a lip on the Roadster and the bracket will not allow lowermost mounting as it hits the seat lip (so just cut off some of the top of the bracket). You NEED the seats as low as possible for headroom and also if you wear a helmet, you need to keep the helmet to clear as well.

Hope this helps.

Steve,
It seems that if BigBirds4RE wanted to fit a wider seat then by removing the door pocket and offsetting the seat more room would be available. Of course that would change the driving position slightly.

Maybe buying a Mondial is a better idea.

 

Sounds like you need to install one of these:

They look nice and could be dyed to properly match the rest of the tan leather in the car, but I don't know if they'd fit... they're 2 inches wider than the Sparco Roadsters (19.25"), so you have a full inch on the center console side you have to be able to accomodate.

 

Agree, that is possible. There is an inch or two still available and if he went with BOTTOM mount he could have fabricated custom brackets. He also needs to be careful if the seats have wider top parts (near head), as you can see they do go wider than the seat itself. The issue of comfort is a personal thing. Some want Lay-Z-Boy, others want tight and firm. i opted for the later and tighten the belts around me a good amount. For me, comfort is when i am strapped SOLID in the seat. Others might prefer a more relaxed situation.

 

I like tight and solid and they don't come tighter or more solid than the ones I build for the Griffith: http://www.pistonheads.com/tvr/index.asp?storyId=2792
However the new ones I have done are about 50mm wider than the standard Sparco Evo.

 

Re 348, keep this in mind. If you get a 90-95 model, they come with the incredibly annoying but mandatory "automatic" seatbelts. The male clip for the shoulder belt is integral to the seat. You'll have to fab a replacement for it and weld it in. Also, the issue with the 348 is WIDTH. There isn't a whole lot of room between the center console and, on the driver's side, the parking brake surround. That's your "max" width. You can pull the center console and/or the brake surround, if you really need to.

vty,

Does it come in red!

 

I hear the new 360 seats are larger, will they fit in 328 or 348, anyone?

 

Would these fit in a 3x8?

Comparing those dimensions with the Sparco Roadster, which i just readjusted in the car this past Saturday (a major PIA, but dropped the seats as low as they can go), i would say those seats at the link should fit.

 

Good. I designed them to fit the Mondial but wondered whether they would fit the 3x8.

 

Basically, take the Sparco Roadster dimensions and you COULD add an inch to the bottom and side width **IF** you use a bottom mount bracket. Tell ya what, i am going to take some pics to better explain things. Keep in mind i use the OMP side brackets and have the seats as low as possible. This provides a low center of gravity and 'adds' headroom.

brb, getting digital camera...


Ok, back with photos. used a tape measure to give you an idea. PLEASE keep in mind the seat is soooo low that you CAN NOT even get a finger under the rear/bottom/back of the seat. it is 'slammed' as low as possible so keep this in mind as for headroom measurements. To mount the seat you need:

A) Patience

B) Blood (that car demands a blood sacrifice during this experience it seems)

C) Mount the Sparco Roadster seat in the following order IF you are using side brackets. You might want to remove the center console and also cut down the small 'L' of an Allen wrench:

1) cut the (elongated hole part) piece of the BACK mounting arm one screw hole level down from the top, as the rear of the Sparco Roadster has a lip that will interfere with the OMP low mounting bracket. To get the seat as low as possible you need to cut one level of the elongated holes top/rear, from the top of the mounting arm.

2) Connect the innermost mounting bracket bottom screws to the car and tighten fully.

3) attach side screws to inside bracket but keep them loose. NOTE: This is a MAJOR PIA and why you might want to remove center console. Also, you will find that the rear/inner side screw has so little working room that you may need to use a long wrench to finish the tightening process. Blood will be drawn, drink orange juice or other sugar-filled drink.

4) Attach outermost (door side) floor bracket to car, tighten screws fully.

5) Attach outermost (door side) seat side screws to the side of the bracket. leave screws loose.

Now comes the 'fun' part... NOT!!!

6) Tighten the innermost side screws fully. There is pretty much NO ROOM to do this unless you fully removed the center console, and even then... So this is why you cut short the small 'L' part of an Allen wrench. Also, you WILL find the rear side screw has ZERO real room (the front side screw has a bit more) so using a long adjustable pipe wrench might help. We are talking about 1/2-inch of working room...

7) Tighten the outermost side screws and you are now done.

And now some pics to display the 'working' room and seat fit. NOTE: there is about 1.5-inches of room towards the door side and ZERO ROOM on the innermost side. Also, i did mount the seat with some incline so the front is higher than the rear. Mounting angle is a personal preference.

NOTE: if you go with a front/rear sliding BOTTOM mounting (unlike my side mounting) you could offset the bottom mounting holes about 0.6-inches to give you a wider bottom seat area.
