Yes, you have to remove the original spring perch.

No idea about 615K's. I really did not like the old azenis so I have not given the new ones any thought. Can't lose with RS3's or Star Specs.

 

what sleeve kit did you run?

 

When you get the perch off with a 3lb sledge make sure to protect the threaded section of the shock shaft. Once off use a grinder to remove the small clip that was hiding under the factory perch. You have good foam bump stops from the factory, cut them in half and use the smaller OD sections. Any collar that sits on the c-clip and isnt taller than the shock is fine. You really need to do more reading on suspension/wheels/tires.

Everything you ever wanted to know about DIY ebay coilovers...

 

Ohlins have a pretty serious lack of rear rebound travel which is not good on large whoop-de-dos on imperfect back roads.

Bear in mind that Xida valving has been developed with extensive track testing and thus are biased to track performance - the big thing is hitting those kerbs at speed.

FCM were more developed with autox and backroad testing. It may be that the FCMs are better for daily drivers. I have not driven Xidas so I can't confirm.

 

alright so i got a new set of wheels!!!!! they are 15x7 though... not as wide as i wanted but i couldnt pass up a wheel i have wanted since i was 15!!!!

 

So they are 15x7 +41 offset. 4x100 of course. Weigh in at 17.5 lbs though. But beautiful! Now need to decide on tires

 

oh nice, will look great on your bimmer.

 

yupp how did you know they were for the bmw and not my miata....

 

what else would those go on?

 

well if i recall correctly certain miatas had bbs wheels, bmw had bbs wheels some mercedes had bbs wheels, there are very a many vehicles that come oem with bbs. so i would assume i could place these on any damn car i please!

 

yeah i know, but they belong on e30s.

 

and whatever else car someone wants to put them on. But yes this exact set was off 89ish 325ix..... Werent available in the states in this sizing and offset... and i like em....

 

The Miata BBS wheels were 14" and weighed ~10lbs.

Does this help with the spring perch question or make it more complicated?

 

i will look that thread over in the morning. and yes miata ones were 14's but 14's wont fit my car. So.... next best thing, and better than current 18's and the 16x7 rota gt3's i was gonna use. so i believe it is a better direction.
