Thanks, here's what I used for med grip carpet. I have plenty of larger springs that's why I opt for larger retainers. Since those short shocks use smaller diameter spring.

3 hole piston
42272 HL cylinder
42192 large spring retainer lower
42167 large spring retainer upper
388cst ae all around

I also have a spare set of the large diameter retainers and plan on using them on mine as well. I'll start with the 3 hole then try the 2 later to see if the feel is different.

Default 418 ballstud height vs 417?

Hey guys,
After snapping TWO Raceberry Hard 417 chassis (one carpet, one asphalt) I've converted my mixed 417/418 to a full 418. I am using the old style ballstuds and was wondering if someone knows the height difference between the standard Tamiya ballstud compared to the 418 ballstud with the "built in" spacers? I had assumed it was a 2mm height difference but not having 418 ballstuds on hand I am mot so sure!

It makes it hard to figure out how much spacer height to use when comparing 418 setups that are using 417 (old) ballstuds vs the taller 418 ballstuds.

Looks great! I was running Raceberry short 417 towers and the 57.5mm short TRF shocks. I found that standard length springs would require the droop screws to set ride height a NO NO!! So instead of using M05 springs I used Xray 4S springs which are 20mm--same length as Mini springs. The Xray springs are large diameter and work awesome. On high grip carpet the linear 2.6 front and linear 2.5 rear gave the best balance. On asphalt the 2.5-2.8 progressive and 2.3-2.6 progressive would be where I'd start.

Thanks, I agree that's why I'm using large retainers to utilize my larger springs. I wanted to avoid the standard springs all together. I didn't realize raceberry had short towers, I should've checked tonisport.

It's 1mm higher for the 418 ballstuds, where they are used.

Sad to hear you're letting go a great car. I understand the local support thingy although I don't fully agree with it. Good luck on your sale.

Agree the locating lugs are a nicer solution, but I think it was a conscious choice to go with the 4 screw setup - the Japanese TRF drivers cars are often pictured without the lower 2 screws which adds a lot more flex (and potentially tweak if you crash)

Any know if there is a pin height difference b/t 19804784 (1A/1XA used on 418) and 54172 (used on 417V5 and TA05II)?

I emailed that company. They said $130 shipped to USA. I'll pass for that price.
