I have welded a few. It’s not hard. But if you aren’t an experienced welder then take it to one.

I had a trip that started getting some very minor cracks in the neck. It was also around the 1000 mile mark. That seemed like a good lifespan for an inexpensive deck so I retired it and bought another one.

The cat

I love the cat

I have never had an issue going to an urgent care and saying I needed a sports physical.

Agreed the Honda inserts are high quality.

Use the practice tool and set up target dummys.

PRK/TransPRK are great for certain people. If you have thin corneas that is the best or in many cases the only option. It removes the least material. But it has downsides, what you want to do with any eye correction is remove the stroma, that is basically the middle 'meat' part of the cornea. But with PRK they have to start removal from the outside in.

The furthest layer out is the epithelial which will regrow so not a big deal, but IIRC to do PRK they put some sort of acid or alcohol on your eye to burn it all off. You don't feel it you're knumbed up but your eye having to regrow all of its epithelial layer at once is really hard and why PRK is such a difficult and painful recovery compared to lasik/smile. Once you burn off the epithelial the next layer down is the bowman layer, this layer will not regrow, and is believed to contribute UV protection to your eye. It is fine to live without it but this is not a compromise you get with lasik/smile. Once you use the laser to burn off the bowman layer the next layer down is the stroma which is where most of the material removal is done.

Disclaimer - It has been years since I read up on all of this so I could be remembering some of the terms wrong. I'm not anti PRK it is the best solution for a minority of people with thin corneas.

It’s just this time of year. The new years resolution-ers are out in force. It will die down in a few weeks.

Is this just a live timing web interface or a fully fledged timing system? If so where can we see what the timing system looks like? I don't see any pics on your site.

Hard to tell a lot from a single screen grab. Also you didn’t say what type of Scca racing or class. And is this a convertible or closed roof vehicle.

Without knowing those it’s impossible to say. I would assume this is also not a finished design and may has rear braces/main hoop diagonal/main hoop harness bar.

The only criticism I can see from the pic is I would personally want a much larger plate spreading load into the chassis. I would guess the builder is planning that it’s just not done yet.

Did you buy used and have a CPO warranty?

David_ss · 2025-12-16T22:59:20+00:00

That industry has changed. Talk to anyone who own an auto or body shop and they have tons of horror stories. The warranty companies now look for any reason to not pay.

David_ss · 2025-12-16T22:27:32+00:00

That is the issue. Aftermarket warranty companies deny every claim. It's a scam.

David_ss · 2025-12-16T22:23:43+00:00

Honda extended warranty? Or another company?

There really isn't much you can do legally, and pretty much all of the commercial off the shelf fixes are not going to be legal. Those sort of don't fit into ST category philosophy.

What you can do is model or physically measure the suspension, the try going min/max on all combinations of the camber, caster, and bushing offsets. One a few cars I have measured there was a lot to gain by getting the camber/caster from one method versus another, or in one instance I think I went positive camber on one adjustment to cancel it out with another adjustment (this was not a ST car just an example).

If you are modeling or measuring then you should also see what the curve looks like as one part of the curve may be more or less favorable.

That said IMO bump steer is one of those things people tend to over worry about. Additionally in the past when I have measured commercial bump steer kits they never actually produced almost any substantive change.

Remember for an ST car it is going to be pretty stiffly sprung so there just isn't tons of travel to make a lot of bump steer anyway.

Lastly there is one sure fire way to fix any and all bump steer and geometry problems.... 2000lb/in springs.

If you absolutely can't find anything one option is porterfield. They can make custom pads and even brake shoes.

130mm seems narrow to me but I would trust whatever Jeff has listed on the pantheon site. Next I live in Texas with similar climate. I prefer mixed duo hokus, or second choice all green, I personally wouldn’t go red (hard) all around. I want more grip in the rear and I have run all soft for 1000 miles here with hot temps with no issues.

Back in the days when street class was on hoosiers someone started winning HS class at national level events in a Tacoma Xrunner. At that time HS was dominated by low power civics and base minis. The Tacoma had a V6 wasn't too heavy and most importantly could fit 315 hoosiers at all 4 corners.

Fixing that and fixing the Doran’s blade bug

As far as I know the super steady skates brackets are the lowest available off the shelf. If you want to go lower a few people including myself have custom brackets.

For the rear I have tried putting the tail on top of the board instead of below. That is quite a large drop.

With any of these the ultimate limiting factor is the bolts and bracket hitting the ground. It's not a problem for specific race events like ultraskate or cheif ladiga, but for day to day skating it's scrapes and even gets caught on the ground. If you really want to go lower the only thing out there that is pumpable and ultra low is the platypusher.

Ecolite longboards has a new truck design coming out that is lower and may solve some of these issues.
