At 60k I'm thinking about doing some preventative maintenance and replace the stock engine mounts to some performance ones.
Looking for any feedback as to which ones people recommend, have looked at the RSS ones, Rennline & 9Products - Solid or semi-solid Question

Nik. I have used Rennline adjustable semis on my gen1 thought they were great I used the softest yellow or yellow .
other really like the RSS semis ,

I have recently been looking at the function first option, they use an OE engine mount filled with urethane which sounds very interesting but I have yet to fully investigate and read reviews

I like the sound of those function-first mounts, not silly money either.

I agree its a promising option I just need to read the reviews and make sure they are as good as they seem in theory Thumb

I'm glad you started this thread as it saved me the bother Grin

This is a mod I wasn't going to do but, my suspension needs freshening up so, I'm going to get some h&r springs with new top mounts all around and get the engine mounts done at the same time.

Been meaning to do it for ages now but, money been put elsewhere ( not on drink or loose women) Grin

I fitted a short shifter back in the summer and that was superb.

Am I correct in thinking the semi solid mounts will improve shifting ?

That's what I want Grin

Yes Ian it will, and the trans mount insert even more but with some added NVH that may be too much for some people , I lived with the FF transmission mount insert for a year then removed it. from a thread on here from Alex the power flex trans insert has been modified now and has much less NVH

Cheers phil.

Mines great at minute. No slop but notchy when cold ( normal) I'm still wanting a bit more from it and couldn't put my finger on it frustrated

This might be it.

Just love giving in the beans in 2nd 3rd 4th and sometimes 5th on the mountain roads which, are within 5mins Grin

Thanks Phil, I was looking at the Rennline adjustable ones. Mine is a tip & I don't track it, so I was thinking that instead of going for OEM I'll go for an upgraded mount with the softest setup, plus they must look cool in the engine bay Very Happy

Nice one Finn Thumb

If I balance the blips right, I can get the engine to rock the back end , which I find amusing and also very cool Grin

Maybe it shouldn't but the sound and the little twitch shows how aggressive these cars really are Grin

Fitted Rennline semi solid mounts and love them. :thumb

Started off on the medium blue inserts but currently running the yellow ones as wanted to play around with difference in NVH. Unfortunately I removed the powerflex gearbox mounts as the same time as switching the engine mount inserts as they were the old design and made a helluva noise so not sure how much the reduction in noise was due to the engine mounts.

Might switch back to blue soon and see... either way much much better than OE mounts

Yes the good thing is you can play around with them Carrara monkey is running blue over yellow and he loves it. Looks Like Mike was running Blue and now Yellow I ran with Yellow so plenty of options to get it just how you want it for you. Thumb

Local indy did it in less than an hour. Up on the ramps, support under the engine, drop the car down so weight of the engine is supported, then I think it's just 2 bolts either side to undo to remove the mounts. The inserts just pop on and off.

I imagine if doing it at home with a jack and axel stands it would take quite a bit longer but would still be a fairly simple procedure.

it's quite an easy job and doesn't take too long, there are 2 bolts underneath the car and 4 holding the mounts in place from the top. This guide says 3 hours but I don't remember it taking that long.

Today I ordered the function first semi semi solid engine mounts , after several emails with Luka the Owner about the differences between the rennin/rss semi solids and his new OE mounts that are then filled with urathane. I couldnt find much on the internet about them but he gave me the confidence to try them as they dont have the NVH of a semi solid and as IMO that wasnt much anyway when I used rennline semis on my ge1 I can only assume its negligable if any NVH but will give me the wins that come by fitting semi solids.
I will keep you posted when they are fitted Thumb I am hoping this will be one of those OEplus mods
