19" wheel question

[andrewlloyd]

Looking at replacing the standard r7 17 wheels with jade r but want the concaved rear look .looks like this can only be done in 19" x8.5 at rear and 18x8.5 at the front .has anybody else got 19s and how does it affect ride and handling I've got the adjustable racking red shocks

[Jhonno]

Will make it ride harder.. Due to the lower profile will be snappier also.

The rest depends on the weight of the wheel.

[jamieduff1981]

It rides and handles much better on 17" RL7s than it does on 18" Spiders in terms of harshness, tramlining etc. I'd extrapolate that it would become unenjoyable on 19" wheels, but YMMV.

[Steve_T]

Ridds ran 19s iirc, not sure if he still does.

[h16abl]

Would'nt having the adjustable suspention take some of the firmness side out a bit plus lift the car to accomadate the larger wheels ,or is this just wishfull thinking

[Tanguero]

The best improvement in handling that I made to mine was not the set of Nitrons or the new poly bushes, nor the custom Eibach springs, but changing from 18" wheels to the original 16" Oz Saturns. They made a huge improvement in feel, ride and progressiveness of break away at the limit. Overall I reckoned it took a good second or so off my times sprinting on average.

I don't even want to think about 19" wheels. If 18"s ruined the handling then 19" will be truly horrible.

Oddly changing from the original 17” RL7s with the TVR speck Bridgestone S02s to the 18” Spiders with the newer (in 2002) TVR speck Goodyear Eagle F1s made the ride much better & had no effect on the break away. #

I think the S02 had a very stiff side wall, almost like a runflat ride, so going to bigger wheels won’t always make it worst

But on the whole it will...

[Tanguero]

This was with R888s on both size wheels, so doing my best to do a like for like comparison.

[Luckyone]

I’m sure I read somewhere TVR did not recommend the use of their 18” wheel over the 16” on the new cars, but everyone wanted them so they ended up with excess of the 16” spider.

TVRs are as much about the looks as the performance, also one shouldn’t really be worrying about progressive break away on a pubic road

Simple solution though have one set of 16s or 17s for the track & 18s or 19s for the road.

With the Nitrons set relatively soft & 225/35-18s Goodyear Eagle F1s on the front the ride is smother than a BMW M Sport 3 series. Not sure I’d like to try 19s though.

I have to say I don’t like the 18s on the track for that lack of feedback & unfortunately my simple solution isn’t a cheap one...

[ridds]

It's very dependant on the wheel mass, offset tyre type and shape etc.

I run 19s on mine and it actually drives better on them than the 18s.

It required a fair amount of modding the arches to get them to fit but again your tyre profile will have a huge affect.

For any spirited driving I'd run 17s but I find the 19s are fine for day to day road use.

[ridds]

I also run Protechs with 500lb front and 425lb rear springs and it's not a harsh ride at all.

[andrewlloyd]

So looking at the feed back would be better settling for some 18"with some choice rubber is what I'm hearing

[Random24234]

A little offtopic, does anyone run 9" widths at the front?

Even on the road I would rather have predictable smooth behaviour on the limit rather than something that suddenly let's go, never know when something unpredictable may happen around me but I want to know he car will not add to that.

I have to agree. I'd argue that predictability is even more important on the public roads due to the multitude of hazards, weather changes and contaminants found on the roads. That and that you're not likely to have a head on collision on track and you wont be wearing a helmet.

I'll sacrifice the blingy looks for a car that works better

Lets be honest though.. Shouldn't really be anywhere near that limit in a Cerb on the public roads!

In normal driving no, definitely not. In an emergency situation when some idiot pulls out of a blind side road in front of you? Quite possibly.

[FarmyardPants]

19 on the back, maybe. The problem is horizontal clearance at the front. You'd have to run rubber bands which would ruin the ride. I suppose if you could find something really lightweight then maybe. Agree with Ridds re higher lb springs, the angled setup of the suspension on the cerb means you need higher rated springs than the weight of the car would suggest. Need to sort mine out (and change the spiders for something decent looking and v light)

I was wandering what Jade R was (try using caps it helps reading )

Here are some tuscans wearing some,concaved ones a bit further down that thread, quite nice, but I personlly prefer Rota's like the ones a but further down that thread again...
