Solid lower engine mount hehe...
No offence intended, but have you ever driven a 306 HDi with one on?
I can only assume it's what it'd feel like to drive a giant vibrator
I personally hated it, and for the net bonus of no apparent improvement in engine movement characteristics even with 155bhp/290lbft, I wasn't really sold on it to be honest
OEM always feel crap when they are 100k miles old and 10yrs of rubber degradation, but it's unfair to judge OEM till you've fitted an original.
Just to continue my mini rant. I bought fancy upgraded stiff mounts for my Z4 and in many ways it's just ruined it. Creaking noises, harsher ride in a bad way, and I swear it's made my drop links wear faster and start rattling as there is less give in the main suspension now.
As much as many of these things sound great, they just are not. They are shit to put it bluntly. The Z4 is known for riding like shit already, people think their cars are stiff and then after 10 miles in a Z4 on your average road they have a new appreciation for how nice their sports car is haha. I think it's quite ok so I think that puts it in perspective how tolerant I am of a firmer more in yer face ride/feeling of the road.
But honestly, those solid engine mounts are NOT something you will appreciate in any way shape or form unless you are planning on tracking it, probably for competitive reasons, as it's main use!
Otherwise the positives it brings to the show are totally offset by it's complete lack of consideration for NVH and road use.
Mini rant over.
Very interesting build so far.
My 2p, you can't double everything. There will be a compromise somewhere.
If you can double economy and double handling/grip easily, or even boost both for net positives by say 25%, then you should go work for an endurance racing team
Not trying to put you down or anything, but I think you'd have more fun forgetting the lateral g's and handling thing. Subjectively AND quantitatively the 306 isn't really bad out of the box for handling, and without going for slicks you won't get near 2g.
Even with R888's and totally optimised everything you'll probably only add 30% to lateral g's vs Eagle F1's or similar on a standard car.
And with R888's you are gonna have horrible tyre drag, wide tyres will also cause more aero drag...
Funnily I was thinking the exact same thing as you, but just go for eco.
Get some narrow eco tyres, lower it a bit to reduce aero drag, reduce weight to say 950kg or maybe even 900kg. Remap and intercool for a decent power figure but focus on the 2000-3000rpm range for economy.
Spend a lot of time reducing aero drag. That is the thing costing you about half your fuel at 60mph as standard.
All very fun and interesting any way, can't wait to see more!
