Most amazing wife's reaction and indulgence towards mods on her car... I am so jealous!!! LOL

It depends as in the case of MY/M3 the shock travel itself isn’t the issue as much as suspension arms changing alignment a lot across the motion arc and range. Lowered or raised the issue is suspension arms shifting out of alignment at extreme ends. Properly designed system will address arms...

The inherent issues are in the space and lack of it. Aftermarket suspension still has to work with the same constraints of lack of stroke and high dynamic alignment changes. But properly designed aftermarket solutions offer higher degree of adjustments and higher grade components to make the...

I feel like waking up a very old thread, but it kept popping up in my Google results for other things, saw it often. I felt compelled to write something about it, as I have been an engineer of monotube suspension systems at Tom's Racing, RS-R Japan, and Cusco Japan, and now on and off at UP...

We are looking forward to having you attend TeslaCorsa! We will be on track rain or shine! The specific schedule of run groups will be sent out to attendees a 1-2 days before the event. This is an all-day event beginning around 8 am and concluding roughly 5 pm although you are welcome to leave...

Even with fresh alignment taken on a static rack, things can move around quite a bit, with grippy tires loading significantly under braking and acceleration loads too. Toe will flex out of alignment with bushings flexing out of alignment, etc. So be sure to inspect all of the arms and bars...

Even with the power to weight equalized at the wheel, after the compensated figure (WHP), the Tesla and many other similarly equipped BEV have a simple and huge advantage over ICE cars in that the most of these BEV have nearly 100% of the torque available from zero rpm. This is VERY different...

May take time but now that I am at UP, I will start to validate things like this more often and bring you results :D I'm seeing more and more things like Model Y's towing things and Model 3's on raceways, little things do add up. Trust me as I have been in motorsports from SCCA to Japan's Super...

It's still the middle of winter, but is your car ready for spring and summer warmer months? Tesla cars perform really well in warmer climates and are best enjoyed in the summer for travels and local trips. But one of the stress points of a Tesla is the drive unit. It's basically the equivalent...

Not to point to any specific bushings or product, but all suspension bushings in general, when stock rubber, can flex and send the alignment off by quite a bit under loads. Here is a video we did and look how much displacement is taking place with stock bushings.

Hi, just another pointer. From softest up to 6 clicks up, there is a fluid bypass in the system on UP coilover, which tends to soften medium to high-speed damping. So from 7~10 click up, you should see a significant change in rebound control and a slightly sharper compression feel. Where it...

Spotting S-Apex in SoCal... Moto Miwa - Unplugged Performance

Thanks!

Our recent outing with UP's Tesla Corsa Track Day. Here a customer S-Plaid is fully accelerating out of a S-corner on the west side of Buttonwillow Raceway. See how much lift the front end exhibits from sheer g-forces and torque at the rear wheels... Amazing cars in terms of defying physics...

Carbuzz's article here explained it in detail... Tesla Model S Interior Presents $30,000 Vegan Leather Cabin At Petersen Automotive Museum "This material is 83% plant-based, weighs one-third of cow leather, and has a 33% lower carbon footprint than your average animal leather product. The...

Velocity International Events in Monterey, CA, is quickly posed to become a second and formidable rival event series to the famous Monterey Historics Reunion. Although this event is held in October, the presence of luxury, exotic, and classic car restoration/racing firms are genuinely...

More and more the deliveries of S-Apex builds are going out of the factory here at UP. Without going into much details, I’m just posting pictures here because it’s just such a pretty car to stare at…

So elaborating on the previous thread about Advan Team Taisan Model 3 in Japan... While it has been racing for 3 seasons, the car really is made up of parts that are not made of complete unobtanium. The brakes on the car have been something widely available on the UP website and so are the...

It's such a fantastic feeling to come to UP and still find my old friends and foes at the top of the game going at it. It's been a while since I retired from National Championship stuff, but I'm loving to be vicariously supporting through Cusco and RSR, before, and now with Unplugged...

Thanks so much for patiently waiting for the arrival. :D :)

TESLA CORSA 24 at Salzburgring, Austria Tesla Corsa 24 at Salzburgring returned for a second consecutive year. Tesla enthusiast drivers converged from all over Europe to experience the special Tesla-exclusive track experience event, many driving in from Sweden, Germany, Czech, and other...

Team Taisan, to the Japanese racing community, has been an undeniable and one of the most consistently winning privateer operation. Its famous Yokohama ADVAN livery has been a notorious and prominent color for Taisan since the mid-1980 and tradition haven’t stopped today. They have won 117...

The type of tire, and make and model of the tire impacts handling, noises, and comfort far more than size differences. With tires chosen being the same, there are some differences yes. But in general it character of the tire is in the construction, design, and materials. Given the car has...

Hi The TEIN FLEX Z is their economy line with twin-tube shock system, so the performance and feel would be something entirely different with UP's Monotube systems. TEIN has higher end Monotube systems which may compare more to the UP fairly. Of course, there is a different barometer for...

Or better yet, fill it with hard plastic inserts like most JDM tuners have on older 90’s cars. We used to call them rigid collars and it was alloy or plastic shaped to fit into the gaps in the bushing and also sandwich it between two plates to solidify the bushing but leaving the rubber parts...

Pilot 4S are very specifically summer performance tires, very narrowly optimized for dry pavement with some wet pavement capacity and enough durability and compound flexibility to cover most conditions on mild climate areas. It is in no way designed to handle ice, snow, or dirt trails...
