silverfrost Posted April 26, 2019 Report Share Posted April 26, 2019 Very nice indeed, nice aggresive stance Felgenfuchs has a very good reputation, a lot of folks using them on the forum Quote A Link to comment Share on other sites More sharing options...
pureguava Posted April 26, 2019 Author Report Share Posted April 26, 2019 Yep - they were very good to deal with. In case anyone wants to look at doing this I used the 3.25 inch lips for the rear and the 2 inch for the front to keep the fronts stock size. i initially did it as my lips looked terrible and thought may as well try the bigger rears... 2 Quote Link to comment Share on other sites More sharing options...

When you move off spec with wheel / tyre size, offset etc etc , then expect little differences .. Unless you are connected with your Esprit's handling like motor sport drivers are , then you will not appreciate the subtle differences which happen , and probably wont drive the Esprit aggressive enough to have any real effect.. But you should still be aware.!!! A lot of us can really feel when the tyre pressures are wrong on our Esprit, and i am not talking by a lot , just 3 or 4 lbs can be felt. This in main is due to the fact the lower pressure changes the contact patch and how it reacts in corners , in turn this also effects the slip and scrub angles. These influence the handling of the Esprit which is what you are feeling.. So in brief , be aware when you change one dimension you can influence another... This does not mean you can not benefit from changes, just that you may need to tweak a few other things to get the best from them.. For the best advice regarding wheel /tyre changes , go to a motor sport shop that sets up race cars. They will have a much better comprehension on what is needed for the changes you have made to get the best from them.. I am a big supporter of Changes , and @pureguava wheel/ tyre set up looks much improved . But we should always remember other factors may need consideration when going off spec.. 5 Quote Link to comment Share on other sites More sharing options...

Couldn't agree more - great post! - these will subtlety change the geometry but I have to be honest - It might make me a massive poser but I fell in love with the esprit for its looks - the handling / performance is a massive plus. I can't kid myself that I can ever get enough out of this car to justify its performance- I just don't do enough track work.I also think this car shouldn't be abused to the point that I will notice the difference that 315s vs 285s make - I have other later vehicles that can fulfill that duty. The big problem I had in every day driving was rear wheel spin - the 315s help with that so maybe just what I am looking for. The front 3/4 view lets you appreciate the stance with these wheels and I am surprised I don't have pictures from that angle - I will address soon!! 21 hours ago, silverfrost said: Handles like its on rails i should imagine.....

Popular Post Jacques Posted November 22, 2019 Popular Post Report Share Posted November 22, 2019 I use the adjustable upper rear arms, plus I went for the Sport300 setup in geo. I kipped the rears apprx. 10,75mm inwards top to bottom. How it drives? Certainly not worse. I'd say better, and I don't really have too much scrub due to ackerman. It handles really well, and I just ecperience the boundry for it's performance has been moved up a further step. As I've been writing before, i actually got a bit sizzy in a roundabout going faster and faster. Acceleration? Still blazing. Braking? Good. Tyre wear? Actuallt surprisingly good. Quick correction in corners that shows a "surprize"? Easy peasy and well behaving. It's glued to the road. No strange under or oversteering. More like neutral. Reverse parallel parking? No powersteering, but not too bad really to be honest. Any bad points so far? Nope. Not so far. Let's see what it does once new suspension in in place. Lookwise? Well I only got super positive feedback from this setup. One may argue that the shaping of the outer rings from Felgenfuchs is a bit different with a part of it being angled differently. But I think they look good. Btw. they are so polished from factory, that they actually look more narrow that they are, because of reflections But the 5 star bolted looks are not for everyone. They certainly look smaller than 17" front and 18" diameter rear, because of the design, compared to say AWI Monoblocs. Well, I like them all. Keeping the wheels nice? I habe been using this all season this year, and I have used a small fibercloth once every two weeks. No water, no chemicals, no nothing. It just keeps on shining. Nothing sticks to them. By a mile and then some, the easiest wheels to keep nice, I've ever had. Well done, Pureguava. Kind regards, jacques ps: I like trains. A lot more than diesel cars... 3 1 Quote Nobody does it better - than Lotus Link to comment Share on other sites More sharing options...
pureguava Posted November 22, 2019 Author Report Share Posted November 22, 2019 Fantastic- it looks great I love the SE wing probably most of all of them. Did you have to dremel off 140 30 year old oxidised nuts like I did ? So much fun 1 Quote Link to comment Share on other sites More sharing options...
Jacques Posted November 23, 2019 Report Share Posted November 23, 2019 Nope, no problems at all. I just sprayed them a bit, then let it stay for a day, sprayed again and then they all came off like new. I did resurface all of the original nuts (well, a company did that). And I cleaned and hand polished all the bolts before reassembly. They have to be dead clean before tightening them down. So, no problems. But there are indeed many on a full set of wheels...

Giniw Posted November 23, 2019 Report Share Posted November 23, 2019 (@Jacques Did you put thread lock on the bolts by the way? It would need a very slow curing one with so many bolts to torque tighten properly?!) Quote Link to comment Share on other sites More sharing options...
Jacques Posted November 23, 2019 Report Share Posted November 23, 2019 Yes, I did. You have to do that. Blue medium Loctite. Not a line, only a drop. The process is to insert 4 bolts and lightly tighten the nuts. Then you go to a tyre fitter and have it centralised 100 %. Or do that yourself. Then mark those 4 bolts, now tightened a bit more. with a sharpie. Then insert all of the others in a multi criss-cross patern with loctite and tighten over 3 sequences. Lastly do the other remaining 4 from the beginning. That way, it's done correctly and is radial and centralised. Important. After that, you can lay two beads, cure, then a third bead in the middle. It sounds like a lot, but it is not that much. Just to make sure it doesn't leak. And I used air bubble free, acid free, heat, cold and water resistant stuff. I did not use any sealant between the middle "star" and the inner and outer rings, to avoid any hill/valey patern. and I made very sure that all mating sufaces were really clean, with no traces of old sealant/corrosion/dirt etc. Kind regards, Jacques 1 Quote Nobody does it better - than Lotus Link to comment Share on other sites More sharing options...
Giniw Posted November 26, 2019 Report Share Posted November 26, 2019 Thanks, so the idea is to tighten four bolts fully at a time. I wonder if a dry thread lock wouldn't be even better as it would allow(?) torquing the bolts more evenly ... (never used a dry one so I am not sure of the "curing" time since it's already dry %)) Indeed I have already read that one must not put any sealant between the rims and the disc to ensure it seats properly. Thank you for the details! Quote Link to comment Share on other sites More sharing options...
Jacques Posted December 2, 2019 Report Share Posted December 2, 2019 Well, the idea is to only work loosely on just 4 bolts untill you have it all centralised. Then work as described in a criss-cross patern, over 3 tightening specs. Then install the valve and it's cap. Then you go to check it all again by measuring it up and rotate it on a good wheel balancer which can also measure the pressure that the wheel gives on to the "road". It varies all over the circumference. Then you can lay the beads, and then you meadure it all up again, and the you can install and rotate the tyre to suit. Working with the road pressure will bring the weights down to a minimum and give you less tyre wear and more precision. When first assembling the central "star", the inner barrel and the outer lip, remember to align the small marked numbers on each part "1", for all parts of one wheel. "2" for the second and so on. It also relates to the valve hole in the wheel/position of the valve. Kind regards, jacques 1 Quote Nobody does it better - than Lotus Link to comment Share on other sites More sharing options...
