Seller Description

Price is $18,000!!!!

This listing is for an 1998 M Roadster that is heavily modified for track use (S54). I know, the 98’s came with an S52…please keep reading. I’ve owned this car since June of 2014 and it has been absolutely wonderful. I picked it up from Orange county in 2014. Its original condition definitely reflected the fact that it was the cheapest M roadster on the market at the time. Since then, I’ve done a couple things to it:

Branded Title (have pics to show repairs from mid 2000’s)

S54 conversion from a donor e46 M3 (engine and trans had 98,000 miles when swapped)
Service on engine: rod bearings, VANOS seals/hubs/solenoid, valve lash, fresh gaskets, cooling 2018
Full S54 conversion harness from Kessel 
Full length headers (megan racing)/full custom 2.25” exhaust (not too loud)
Jim Kessel did the tune
E46m3 engine harness with factory DME
CSF radiator/Derale 19 row oil cooler 
Custom power steering lines/cooler to prevent boiling fluid (works well)
Getrag 420 6 speed 
New dual mass flywheel from 2018
New oem clutch also 2018
3.62LSD diff rebuilt in 2018

TCK single adjustable coilovers (400lbs front/500lbs rear)
Brand new bushings all around (front arms, rear subframe, engine/trans mounts AKG everything)
IE weld in tabs for rear camber/caster
Vorshlag front camber plates
New guibo and center support bearing

Welded/reinforced front strut towers
Randy Forbes Dual Ear rear reinforcement (all sealed and done correctly)
Alignment specs for front are -2.8* camber and 0.10 toe in/rear is -3.0* camber and 0.15 toe in
Corner Balanced to 51%-49% front/rear and 50/50 cross. Total weight is 2900lbs

Sparco Pro2000 driver and passenger seats mounted with VAC driver and planted mount for passenger
CAE shifter 
AIM MXP strada dash with GPS 
AIM sensors include: oil pressure, oil temperature and diff temp (along with S54 can bus for everything else…RPM, tps, ECT…etc) 

Front is Wilwood SLR 4 piston calipers with 332/32 slotted 2 piece rotors
PFC 08 pads
Rear are oem calipers with Gloc R12 pads
This brake set up has 2 track days on it so almost new. At least 14 hours left on the front rotors and more than that on the rears
Bimmerworld brake cooling plates installed (the ducting hoses are currently removed and do not come with the car…I destroyed them at the last event and have not replaced them)
Stainless lines all around
I ran motul RB660 in this car, brake fluid hasn’t been changed since 2019 so probably not a bad idea to do that. 
Brake feel with this set up is phenomenal.  No brake fade, no boiling of fluid, no pedal mush, no issues whatsoever. I’ve ran factory calipers, 996 calipers and Wilwoods on this car and the Wilwood set up is by far superior (having 2 piece rotors is the major advantage in cooling). 

The car will come with SSR Type C wheels
17x8 et 38 front with 225/45/17 Hankook RS3 tires (these are old street tires with plenty of tread, just not good enough for the track)
17x9.5 et15 rear with 255/40/17 Hankook RS3 same condition tires. Date code is 2016
Extended studs all around with a 10mm spacer out front and 15mm rear

I know it seems like this car is primarily set up for track use but its still wonderful on the street. Its nimble, quick, and still very appealing (especially for its age). This car is, however, not perfect. I’ve never really cared about little dings and tiny scratches. For the first 4 years of its life, I only drove this car on the street. Ever since 2018, I only drove it to and from track days. Everything has always held up great. Oil changes twice or more per year. Trans fluid change at least once a year (along with diff fluid). Current fluids in the car are all from this year. 
Reason I’m selling it now is due to my car situation, I have too many and this one doesn’t get the attention it deserves. I recently picked up a z3 coupe and that has taken the place of a track car for me. Now, the MRoadster mainly just sits around waiting for its turn to get on the lift for maintenance. Its time for someone else to really enjoy this thing for what it is. 

Car is currently in West Chicago (Chicago suburb west of Addison). It sits at my shop space and can be put on a lift for a full inspection. Can be viewed there anytime so long as we agree on a meeting time (takes me a while to get out there). 

There are some Cons with this vehicle:
Window regulators are slow and get stuck a little sometimes
Minor scratches and dings
No fuel gauge 

Absolutely NO RUST! For any serious buyer, please contact me and we can go over any questions you may have. This car is surprisingly comfortable for having bucket seats. I wouldn’t hesitate to get in and drive anywhere in the country (if you’re brave enough with the heat). All this thing needs to be a competent track car is new tires of your choice (and brake fluid flush just to be safe). 

Please be respectful of my time. I’ve done my best to include everything I can think of in this add. I’m happy to discuss price over the phone (especially if you’re not local), but all lowballs and price spams will be ignored. I’ve poured hundreds of hours into this car over the years and would like to see it go to a good home. 

Some trades I would consider with cash going either way are: e46M3, e90m3, Cayman, 996/997, lotus, super clean k20eg

Thank You for looking.

This is a pretty cool conversion and would definitely be a fun track car. It's full of great parts in addition to the S54 and hard top.
