Re: Highest Quality Suspension Parts Master List
That sucks. I think someone on Preludepower had to turn down the rear tie rods to M12x1.25 to use them. I may need to investigate adapting those aftermarket 2WS toe rods (or just the rod end) to work with the 4WS setup.

Re: Mugen MF204 Detailed Pictures
Unfortunately the B20a only ever came in 88-91 Preludes so it doesn't have much aftermarket support. But there are some options for pistons+rods, https://motiveforceperformance.com sells them.

Slightly Extended Studs
If you want longer studs without going with the super long "tuner" studs you can use Dorman 610-408 studs (they are sold as a 10 pack). They are 12mm or almost 1/2" longer than stock. The center caps on the OE wheels will still be able to fit.

It has had a loud drone that peaks around 3300rpm, which sucks because that is a typical cruise rpm. I was on the verge of buying a more restrictive stock style muffler because there is no room...

I would start by checking all the grounds. After that I would probably look at the igniter.
