most people will suggest going with the 88. but i had the 88 and it caused way too many vibes for me. the entire car shook when i was accelerating between 900 - 1500 rpm. u could hear the shaking outside of the car too. i dont kno if i got a faulty mount or something but i had to sell it.
but like i said most people on here are running the 88 awr. just letting u kno what happened with mine.
88 is the way to go. 70 will be more forgiving, but in most cases you won't feel the vibes. My car is bad with the A/C on at idle, but other than that it doesn't even phase me.
I'm holding my used AWR, and this thing has absolutely 0 markings on it. Not a which side is up, or forward. Nada. Just gloss black paint and red bushings. First owner says he thinks it's a 70 but not sure.
Does it matter which way you install it? It looks like it could fit any way.
