years, which is par for my course. At 1/2 - 2/3 the cost of a Moll from the dealer, i would always go aftermarket. DieHards are good too (again). note that most batteries are OEM'd from others, so quality changes over the years. Grantby grant - Main Forum
They stick. They are round (not all that common!). They wear well. I've used them on road and on track, and they hold up on track too. That said, i bought Khumo track tires, Ecsta Sport SPTs. They are, for 1/2 the money, pretty darn good. Took a *little* playing by Euro Tire to get them seated perfectly, but once done - very nice. I have never had good experiences with Bridgestones. bubbles.by grant - Main Forum
part numbers are: 14 FGR 6or7 KQU FGR 6or7 KQC BKR6EK NGK? 6 or 7 is a heat range and depends on year. I used 6. Grantby grant - Main Forum
As i noted when i posted the pics mine had none of that apparent play and the races were fully intact. Despite that, there was NO, none zip grease. It was all splash lubricated with engine oil. 37k, frequent oil changes, always driven easy until warm, then driven hard. 17 DE days + similar AutoX. Grantby grant - Main Forum
(actually, thought i said all that when i posted my pics). in fact i was at the point of intentionally revving the car out once warm a lot - its certainly fun medicine anyway. Its very interesting that very few tracked cars fail, and those that do are the ones that are driven at the track *but then stored*. And once the flywheel is off - its right there.

for two reasons. 1. it was introduced in 5w50. See my various rants above about wide ranges and the requisite VIIs. SO the first product out the door had great specs but suspect quality. Sorta like a F458 made by Yugo. 2. The early Syntec did not (reputedly) have the same quality base stock as early Mobil1.

We dont know all the facts of course. But we do know two things: 1. Mobil's base stock appears to be in the phase of being cost reduced. Mobil stopped using Group IV base stocks years ago, claiming they were no longer needed. And dancing like crazy in public. They also have multiple M1 formulations at different price points Gold cap vs Red. etc. Marketing led formulations typically are not excepby grant - Main Forum
Many manufacturers spec things differently. The most important number, to me, is the HTHS (high temp and high speed) shear number. It measure ability to protect (not shear) under high stress and heat. You must exceed 3.6 to pass ACEA A3. M1 0W40 for example, passes by a smidge (<3.7). If you read between the lines i told you much more earlier, but cant reference it. Lets say achieving 3.7 mighby grant - Main Forum

in the very old days - and this was a very general rule - those three levels existed. Comfort was OEM. HD was same dimensions but stiffer. Sport was typically HD with a shorter piston, maybe a bit firmer still. I have not seen comfort, except for Benz, for ages. Maybe a decade. And i also have not heard whether the HDs are in fact close to OEM or not. But Bilstein *is* OEM, so it may well be.by grant - Main Forum
.. and presumably stock height. Which does make a lot of sense for a non-track, DD car. On the other hand, I will seriously consider the ROW 030 complete when the time comes for me - but that's partly due to my track time (Where the wonderful slot-car like stock setup suddenly feels like a wet noodle) Grantby grant - Main Forum
For a few reasons. 1. reports are so subjective 2. its expensive to put them in and find out 3. springs and shocks need to be matched for critical damping - more or less is actually bad That said, Bilstein is the OEM supplier to Porsche. So the HDs should be close. problem is, close to what? ROW030? USA stock? I'd go for them over any other aftermarket solution. But maybe you need to bite tby grant - Main Forum
Absolutely, positively, require the use of VI improvers. VI improvers break down - yielding an oil that no longer meets the high temp shear performance suggested by its DC-to_light rating. Worse yet, they can cause film tear in main bearings, and when they do break down, they are a component of sludge. So i always advocate the narrowest range you need - e.g.:L 10w40 rather than 5w40 and certainby grant - Main Forum
This is a simple matter of specs and tests. I have the same use for porsche approved oils that i have for N spec cupholders. It flows well at all but the craziest temperatures. It has far better HTHS shear and durability over cycles than most 5w40 oils It flies through ACEA testing while many need 10-20 repeat to get the coveted A3 rating (hmm, how do i know that?) Is it ideal? No. I reallyby grant - Main Forum

i have no experience, but the reality is that you need to pry them apart. So i'd figure that some form of pry bar and fulcrum should work. Big screwdriver along with another to be a fulcrum? Uhh..... you may be heading to your FLAPS tomorrow. Grantby grant - Main Forum
My mind resides in a strange land where the size and location of IMS rear bearings is common knowledge. Notice we never discuss the bushing at the other end! Grantby grant - Main Forum
