Even dirty ones! LOL

I'm hoping to tackle most of the issues by the end of August.

Update:

Saturday, I drove around my Fiancee's E30 in preparation for emission testing. I have to say, this car is very fun and mechanical compared to the E46.

Specs:
M50 swap
Ireland Engineering Stage 3 Race Springs w/ Bilstien Sports
Recaro SR3 w/ Leman Confetti centers
Euro E30 Clock

The car needs some love and attention to comestics soon but overall its on incredible car to drive.






I place the ZHP on a lift to determine the oil leak and swap spacers.





Oil pan is definitely the culprit for the leak.
I swapped the 3mm spacer for a 12.5mm spacer and the steering vibration amplified on the freeway at 60mph in neutral or in gear.

The last pic I took, I slapped the 12.5mm spacer in the rear and the 3mm in the front. I also swapped the newer ARC8 up front and the rear left driver up to the front driver. Vibration in the steering wheel is still there but far less than with the 12.5mm spacer. I am now stumped. I may buy new tires for the M135 rims or borrow my cousin's rims to test out.

Hope you figure out the vibration.

But I would remove the spacers, clean the hubs and see if the issue is still there.

Thats the funny thing, there is no rust or anything on it..(california car :P )

Long story short:

The ZHP will be up for sale. Official post will be posted once I get proper detailing/pictures. I do not plan to part out the ZHP but if the car doesn't sell, I may.

I'm aiming to replace it with an M car but unsure which model as of yet.

If you don't have hub extenders then I'd bet money on the 3mm spacer being the issue. I had that exact problem with 5mm spacers without hub extenders. The 12.5mm spacers surely have a hub/lip on them so that should work.

That's what I'm thinking too. I'll give it a shot when I get a chance to work on the car.

It's obviously a little late to chime in if you've decided to sell, but I had nothing but problems with 12.5s. ZHPizza can explain better, but it's something about the hub extension not being deep enough to get a good seating. I swapped my 12.5s for his 15s to test (expecting things to get worse) and the vibrations completely disappeared. I have 3mm Macht spacers in the back and haven't had any issues.

I agree

I'm unclear on the issue too. I have 3mm installed and the issue is rather minimal compared to the 12.5mm. I don't remember having issues with my stock 135s on the 12.5mm. The reason I got 12.5mm instead of 10mm was because of the lip issue. I thought the 12.5 was meant to resolve that issue. Either way, it's minimal.

Either way, I'm looking to jump into an M3. The ZHP was originally purchased as a daily driver during my college years. Since then, I now have a commuter car, and the ZHP has been sitting. I think I've reached a point in the ZHP's life where it needs some major changes to be faster in HPDE days. The biggest gripe right now is the lack of power. I maybe able to keep up with some cars in corners, but man, the ZHP just gets walked on straights.

I thought a few ways to do this:

#Supercharger
As a turbo car owner, I know heat is always the number enemy. A proper TS2 would cost me around at least $8k and ultimately fail emissions miserably.

#S54 swap
This is a nice choice but it would be along the same price as the supercharger. If I were to do the swap, I would want to do the flares, do everything. That adds up and then becomes too nice to want to push any harder on the track. That ultimately defeats the purpose of getting a faster car for HPDEs..

#Sell car, get M.
At roughly the same cost as the swaps, I can get an E46 M3 and build on a similar platform with more potential.


I'll miss the ZHP, I hope I can find a good home for it. It basically needs cooling system PM and thats really about it. The rest of the car is ready to enjoy some mountain roads.
