So Ive been handed the candle to the only track-oriented LS400 build known so far. Ive known this gentleman for awhile now and he passed on his seats to me since I was building a track UCF20 as well. So, without further adue, heres mine.

 

Interior shots
Grant NASCAR Winston Cup wheel for era-correctness, HKB hub with a Forever Sharp 6 to 3 bolt adapter.
Bride brackets with Buddy Club P1 seats. Only 16lbs each.
Stripped carpet, doors will be stripped as well within the next week and covered in ABS plastic door cards.

 

I take inspiration from the Australian V8 Supercars of the late 80s and early 90s, the Super Taikyu cars of the 90s, and IMSA homologation. Hence the crazy side exit exhaust. System is 2 into 1 factory diameter exhaust, into single stock center catalytic, out in a 2.25" single exhaust system out this flat tip on the drivers side.

 

Didnt want the bolt on look of the usual riveted flares so mine are sealed on with 3M double sided and some sealant to keep them on. Smooth ZG 240Z flares.
Speedline SL390 wheels, 17 lbs each, 3lbs lighter per corner (also known as Crown Vic PP wheels)
Federal SS595 245/50/16 tires, theyre really 265mm wide though.

 

98-00 UCF20 rear sway bar (stock base '96 sways are 13mm, 98-00 is19mm) for better turn in
Siberian Bushing front and rear Polyurethane sway bar bushings
-1.3° Camber/ 0.12° toe out front
-2.0° Camber/ 0.12° toe in rear

^ sir I think you just thread jacked the OP thread!

 

Haha yeah, unfortunately he isnt gonna continue this project anymore, so Im the only one left doing this so Il be carrying the torch now✌

So new canges lately:
Custom ABS plastic doorcards, and sunroof deleted.
OEM door cards:
9lbs
ABS Plastic Door cards:
2lbs
Sunroof:
38lbs
Sunroof delete panel:
5lbs

 

also, test fitting C4 Corvette wheels, doing 295s all around very soon.

 

Update: door cards hand fabricated, and sunroof deleted.
Also, GM C4 Corvette 'Cuisine' wheels, 17x9.5 with tires size bumped up to Federal SS 595 275/40/17. After alignment should be able to take advantage of the extra tire-to-road

contact. Took it for a spin recently and the roadholding is absolutely superb now. Big girl can hold her own against way smaller cars under hard cornering. Sunroof delete made the handling more neutral as well as more predictable, who knew deleting it would make such a substantial impact?

 

Where did you get your plastic for the sunroof delete and door cards I'm interested.

 

I fabricated them at home😁 used ABS Plastic sheets and lots of cutting. Roof is also fabricated by me, it's a galvanized steel sheet

 

Update: fenders paintmatched to mask the adhesive I added to them to keep them intact to the body. I hate riveted flares lmao

 

I thought it looked dope with the flares black. Still looks great but the black flares gave it that toy-car look we all have liked ever since Polka-dot-door.

 

So more progress has been made, first to show is the livery:
