Dunno why the forum doesn't like a reddit link, but here's the chart from the post:

Necroposting here, but US-standard XL tires (probably what you have on your ITS) reach their maximum load capacity at 41 psi, which is probably why the manual says set the front tire PSI to 41 if doing high speed driving. If you are not doing high speed driving (and staying below 100mph) you...

Damn, that's a lot of variance. 10 to 12mm is basically half an inch.

Was it violently "punted"? :) Some days I think about doing that to mine. It's a good car, but the "spirit" isn't really there for me, and something small breaks every two to three months. Also the multiple forum posts every week about someone's engine grenading while just driving on the...

VHB is pretty nutty strong. If I remember right, the hold power is something like 90 pounds per square inch? They also use it to attach stuff (like fairings, winglets, etc.) to commercial airplanes for flight. I was also skeptical of it until I started learning about it. Modern adhesives are...

There are some EPS racks that have decent feel. Besides the Porsche ones, honestly my Focus RS and C7 EPS racks are pretty great. They're not as good as a classic generation hydraulic rack or manual rack, as far as feel goes, but they are pretty damn good for what they are. Part of the reason...

Yeah, I know a few people that are like that, that let the car basically drive itself and then drive with habits that would be super dangerous if you were driving an older car. But the car saves them, especially the AWD ones. It's a bit frustrating. But I suppose manufacturers have to sell to...

Just my two cents (as someone who does not own an ITS... yet), but I have had the opportunity to rent and drive a different car with a friend each Wednesday for the last ~2 years. We have driven Ferraris, Porsches, BMWs, a McLaren, a Lamborghini, etc., etc. Outside of a very tuned and modified...

My parents have one in their X5 and I have heard nothing but good things, but it does take up a lot of their usable storage space. I couldn't use one in my (likely to be bought) ITS just because there's no room for one plus a mountain bike in the back when doing my long mountain biking road...

A good video on those things:

Thanks! Measuring the springs shouldn't be a problem as I've got some fancy bigger calipers. They probably will be accurate enough for car springs! I definitely could have used those for a few trails I have done in the past with the Focus. None of it has been high speed, just very slow...

Invoking the power of geometry, if the approach angle on the ITS is 10.9 degrees (0.1868 radians), and the ground clearance is 4.0" (according to that Acura specs webpage I linked to)... tangent-1(0.1867 radians) = 4.0" / CenterOfWheelToEdgeOfBumper If I'm doing my math right (it has been a...

Well, today I learned apparently approach angle numbers are things you can get from the OEM specs, so you don't have to measure things directly? Here's the Focus RS...

Thanks! Huh, I haven't heard of spring isolators before. Although it looks like you have to unbolt the top hats to slip them in? Unless you are meaning "spring spacers", which just slip in? Those are also something I never heard of before, but searching for isolators had them pop up. I'm...

The larger tires are an interesting idea, although it would affect initial acceleration due to the extra weight being rotated. I'd have to sit down and do the math. Also, there would be more sprung mass. Tire rack has the weight of a Michelin PS4 265/30R19 as 24lbs and the 275/35R19 as 26lbs...

Hi all. I'm strongly considering an ITS. However, it will need to go to mountain trails, deal with some steep inclines and approach angles, etc. I have been using my Focus RS for this use case for nearly a decade and it has worked just fine. (I think it has less ground clearance?) However...

I agree, but I'm thinking about switching to an ITS from my Focus RS because their engines can randomly grenade when driving! Slightly bit more of a pain in the butt than dealing with a spare tire. For me the full sized spare in the back wouldn't work just because when I'm doing long road...

Yeah, modern adhesives are pretty nuts. The original Lotus Elise chassis in the '90s was put together using just extruded aluminum, adhesives, and rivets. Adhesive tech has only improved since the '90s, and I have never heard of the S1 Elises failing because of adhesive failure, and they've...

Necroposting here (I'm new to the forum and reading all I can about the ITS before maybe buying one), but you can use VHB tape to secure, say, the Mounting Plate for the tire. AI says there is a newer VHB called VHB Max that has a dynamic pull strength of 25 pounds per square feet (edit: square...
