less! Only two lower shock bolts. :-) ptegler

I've always been amazed at the idea that cars rely on just two bolts to support all the weight up front (two lower front ball joints) Cars sits on the shocks/springs sure, but everything presses on that short, lower shock mount to ball joint area of the front lower suspension. REAL or not, the idea that the front weight now sits on top the upright. just seems right for some reason. The Lotus software really can't make any determinations as to whether it's better or worse than other designs, as it for angular and speeds of motion of travel type analysis, rather than 'track feel'. Again, the only way reality can make a suggestion, is a talented driver's (or group) direct comparison 'seat of the pants'. Even then I think I'd still prefer to do that test myself, for a multitude of reasons! :-) v/r pegler

@Marek I think we chatted about a meet up once before. Had Chris's son at least acknowledge my email, but never got a follow-up as promised. So I didn't push it. Funny to as to this day the dealership is still there, albeit diff name/company/dealer etc. ptegler

Cats simply went dual a-arms as nearly every other car out there, most likely simple parts availability and or road testing safety regs etc. Orig Sevens, the leading upper a-arm were the sway bar itself. The rubber end compliance was there as a solid mount would have stressed the upper inner pivot as the sway did not rotate on the same axis as the arm. The Rotus design does not need nor benefit from a sway bar. Take a glance at any F1 car (simply easy to see during TV shots) you see no shock, nor even a shock strut, as their upper arms are the same see-saw scheme (albeit bell-cranked etc) I've got an old copy of the Lotus suspension software. In the past I'd modeled my Triumphs, Miatas, MGBs etc. when working the Rotus suspension measurements, The Rotus design, tests as if a Z-bar is mounted up front! Nearly zero roll with the wheels on the ground in a corner, yet normal compliance of a single wheel over a bump. Probably why they got away with such lightweight springs 125lbs in the back 115 up front (or do I have that bass-ackwards?) Personally, maybe it's the ol' geezer in me.... first hand experience is the only justification for any comments. If you haven't driven both, any comment is mute. v/r ptegler

somewhere back in this thread(?) there are a couple comparison shots of the later cars with slightly longer a-arm ends (less threads exposed) A gentleman her and I had discussed this very point...we compared photos, and it appears longer arms were used later in the production run. Mine also have longer arms with only 1-3 threads showing, and my camber is ~ +0.5° Regarding the BAT poster.... take it with a BIG grain of salt. I'd personally visited the dealership multiple times, almost buying one new in 1988. But the X-wife wanted a 4x4 for all the camping we use to do in Western MD (I'm in Baltimore) Some assets are still in the hands of x-employees in the general area to this day.. Many stories abound, those that gained were happy, those that didn't ....well.... The most I got away with was a sweat shirt 9back then anyway! took another 34 years... but I got one. (and a new wife obviously) ptegler

the Probe lever setup is wild to say the least. One thing to watch.... that switch. that rides the steering column. and the current path for the relay used makes a difference as to whether it self-cancels. .... (relay coil resistance) after the re-wiring (for those who don't know about this switch) One lever is turn (up/dn) and high/lo beams in/out. plus momentary high beams flash all within finger tips reach

EXCELLENT to meet you! ..love to know there were more after mine! Everyone has been limiting the numbers built, vs the actual chassis #'s so stating your as such, fits events to date. We were all beginning to believe #93 (mine) was the highest number anyone had run across. Middle of the country I see. ... East Coast myself. Welcome

how it ended up (three vert rod holes pre-existed so they got used. same edging around my cowl above the dash, wraps the expanded metal. I can just barely (big hands) get my little finger in a hole

no reason to be sorry.... saw the 98 and thought cool! even later than mine so might have MANY similarities. ,,,then saw the 1992. Still though these two should be quite close to the same. Yours is the only other I've seen that used the Ford Probe turn signal/bright lights switch besides mine. (took quite awhile for me to find what that was sources from.... (Factory Five guys on their forum use them)) let us all know as you dive in, what quirks, how the hell.... , WTFs, etc you run across. :-) We're all learning from each other at the same time, old and new. ptegler

as what's on your title... but didn't Custers crew stamp a number on the cross bar that supports the steering column in the engine compartment just forward of your pedal mount assy. .

serial number? (of yours) mine is 1993R0700000093 we look like twins, save my interior is black and it's a tweaked BMW 2 liter (as originally built) ptegler

Fantastic! N / N/E WV? (near their orig origin that is?) he he PICTURES ?!! (please!) and ser# since it's a '93! ptegler

save the engines, the rest of the car appears to be 95% the same parts. A few mods to a-arm lengths (threaded upper knuckle exposure) a couple dash versions, (switch locations, gauges mounted through vs only behind the dash) chin spoiler molded into earlier nose cones (absent later on) I've alos noted a difference in mastyer cyl mountings. ealier seem to be cast brackets, while later cars got fully adjustable position Tilton pedal assemblies. But all still used the very inexpensive Toyota master cyls. Even my M10 powered BMW 4 speed, and the TR8 5 speed used in V8's all used the same Toyota master cyl.

#0 RED at 12 o'clock is master switch OUT, power to starter, and high power feeds (relays supplies) There is a 10ga BRN wire right under that #0 RED, hooked to the master switch ALT out terminal and is the main ALT BAT terminal. at 6 oc'clock, The battery + terminal feeds the master switch PWR IN, and has a jumper over to the ALT IN terminal of that pole of this DPST master switch anyone wanting a fuse block cover,, let me know and I can post the STL file to print your own. Actually.... Rotus fuse box lid.stl ptegler
