lol.. my SO has gotten very used to walking out to the driveway and finding Tesla parts scattered all over
. She's generally supportive because most of what I do is low cost improvements. I'm not tracking the car for example so no new rims at 1K a piece or coilovers at 3K are being considered. I have a RWD partial premium that I got a reasonable deal on. Most of what I'm doing is enhancing the car to bring it up to parity with a newer M3. Simple mods by and large with the exception of the replacement of the entire braking system for the performance version. Thats a vanity project, not something is "needed".
I view Teslas as a "lego" car.. like my old snap together kits. Much of the cars are very easily interchangeable which makes upgrades fairly straightforward with a few exceptions. Some upgrades that are almost impossible to do are really stupid .. like adding in the factory subwoofer. Should be a bolt in and maybe a code update. Nope.. for whatever reason, Tesla changed the wiring harnesses completely. But They did leave in all the speakers so a 75 dollar cable got me all my speakers except the subwoofer. I can live with that. I got my foglights via Ingenext module plus my ambient lighting. Again, something Telsa had there but refused to offer a paid upgrade.
Cost benefit? are you kidding
. If I had done that, I would have bought a M3 with the full premium and probably a dual motor.. maybe. I intentionally wanted the RWD because with my insurance, anything "performance" added a significant bill to my premium. The RWD is just a few hundred more than my Audi A3 and significantly faster than my A3.
I've spent about 1k on toys and additions like the CCS, audio cable update, tail lights etc. The brakes will boost that by 1500 all in. 4 calipers, new pads all the way around, rotors all the way around, dust shields, parking brake cables.. everything. And about 4 months of shopping on Ebay and here for parts. Patience is virtue for getting cheap parts.
My range is 215 miles fully 100% charged. to get 60 more miles of range would cost me 5-10K.. definitely not worth it. Even if I could swap the packs and get someone to code the pack to the car.
My Tesla is my daily driver and a bit of a toy. So everything I do is seen through those optics. Everything I've done is easily undone if I choose to. But I wont. Even the brakes could be undone but it's beyond me why someone would go from Brembos back to the non performance brakes. But after spending 300 for a set of sport brake pads for the rear, I might see why
.. Those rear pads were almost impossible to find other than Tesla. I did find a few, very few after market but they were within 50 dollars of Tesla's price so I went OEM.
Would I do it again? sure. My M3 was 5K cheaper as a RWD short range vs the long range P version. Its cheap to insurance ( for a tesla) and I've never had an issue with the short legs. Is it as fast as the P? Nope.. is it faster than most ICE cars, oh yeah.
